摘要:
Isocyanates of the formula (I) in which X and Y are defined as in formula (I) of claim 1 can be prepared by reacting a compound of the formula (II) or its salts in which X and Y are defined as in formula (I), with 1 to 6 mol of phosgene per mole of compound of the formula (II), in the presence of 2 to 3.5 molar equivalents of a base per mole of compound of the formula (II) and in the presence of an aprotic organic solvent at a reaction temperature in the range from −30 to +60° C. to give the compound of the formula (I). The compounds (I) can be converted by reaction with nucleophiles to give addition products, such as carbamates, ureas and sulfonylureas and corresponding products, e.g. herbicidal sulfonylureas.

摘要:
A [5-chloro-6-phenyl-2-(4-trifluoromethylphenyl)-4-pyrimidinyl-amino]acetamide derivative of the formula (I): wherein R1 is a methyl group or a cyclopropyl group, and a pharmaceutical composition containing the same. Said compounds exhibit a potent anti-rheumatoid activity and show low toxicity, and hence, they are useful as an agent for prophylaxis or treatment of immuno inflammatory diseases such as rheumatoid diseases (e.g., rheumatoid arthritis, Behcet disease, ankylosing spondylitis, etc.) and autoimmune diseases (e.g., multiple sclerosis, systemic lupus erythematosus, Sjögren syndrome, etc.).
摘要:
Pyrimidines of formla (1) are described: wherein R1 is a —XR6 group; R2 and R3 which may be the same or different is each a hydrogen or halogen atom or a group selected from an optionally substituted aliphatic, cycloaliphatic, heteroaliphatic, heterocycloaliphatic, —OH, —OR10 [where R10 is an optionally substituted aliphatic, cycloaliphatic, heteroaliphatic, heterocycloaliphatic, aromatic or heteroaromatic group] —SH, —NO2, —CN, —SR10, —COR10, S(O)R10, —SO2R8, —SO2N(R8)(R9), —CO2R8, —CON(R8)(R9), —CSN(R8)(R9), —NH2 or substituted amino group; R4 is a X1R11 group where X1 is a covalent bond or a —C(R12)(R13)— [where each of R12 and R13 is a hydrogen or halogen atom or a hydroxyl, alkyl or haloalkyl group] or —C(O)— group and R11 is an optionally substituted phenyl, thienyl, thiazolyl or indolyl group; R5 is a halogen atom or an alkynyl group; and the salts, solvates, hydrates and N-oxides thereof. The compounds are selective KDR kinase and/or FGFr kinase inhibitors and are of use in the prophylaxis and treatment of disease states associated with angiogenesis.
摘要:
The invention relates to the preparation of compounds (I) in which A=H or acyl and R1, R21, R3, R, n, X, Y and Z are as defined in claim 1 by halogenation and rearrangement of compounds (II) (optionally salt) to give compounds (III) a) ammonolysis of (III) to (IV), reduction of the nitro group and reaction with carbamate (salts) (VI) of the formula Ar—OCO—N(M)—Het, where Ar=phenyl, M=H or cation and Het=heterocycle from formula (I), to give compounds (I) (A=H), or b) ammonolysis of (III) to (IV), reaction with carbamate (salt) (VI) and reduction of resulting compounds (VII) at the NO2 group to give compounds (I) (A=H), or c) reaction of (III) with cyanates and amines (VIII) of the formula HNR3—Het and reduction of the resulting compound (VII) at the NO2 group to give compounds (I) (A=H) and optional acylation if A is to be other than H.
