摘要:
A process for the preparation of a compound of formula ##STR1## wherein X represents hydrogen, halogen, trifluoromethyl or lower alkyl group; W represents methyl, Q represents hydrogen or W and Q, together, form an ethylene group and R' represents a lower alkyl group which comprises protecting the amino group of the phenol corresponding to the compound of formula I, submitting the compound thus obtained to an alkylation (with a compound of formula Hal--CH.sub.2 --COOR', wherein R' is as defined hereinabove for the formula I and Hal is chlorine, bromine or iodine) and then releasing the amino group of the product thus obtained.
摘要:
The present invention relates to pyridazine derivatives of formula: ##STR1## which are useful as ligands of cholinergic receptors, in particular, receptors of the M.sub.1 type.
摘要:
A process for the preparation of a compound of formula (I) ##STR1## which is a (RR) and (RS) stereoisomer of N-(7-ethoxycarbonylmethoxy-1,2,3,4,-tetrahydronaphth-2-yl)-2-(3-chlorophenyl)-2-hydroxyethanamine and their pharmaceutically acceptable salts.
摘要:
A process for the preparation of phenylethanolaminotetralins of formula ##STR1## wherein X is hydrogen, a halogen, a trifluoromethyl or a lower alkyl group and R.sup.o is hydrogen or a methyl group substituted by a carboxy or a lower carbalkoxy group, which comprises treating a mandelic acid with a 2-amino-7-hydroxytetralin, optionally alkylating with a lower alkyl haloacetate and reducing the amido group of the mandelamide into a methyleneamino group. The mandelamides intermediates are novel.

摘要:
The invention relates to the use of 5-alkylpyridazine derivatives of the formula ##STR1## in which R.sub.1 is a C.sub.1 -C.sub.4 alkyl group or a phenyl group and R.sub.2 and R.sub.3 independently are a C.sub.1 -C.sub.4 alkyl group, or R.sub.2 and R.sub.3, taken with the nitrogen atom to which they are bonded, form a morpholino group, or one of their pharmaceutically acceptable salts, for the preparation of pharmaceutical compositions for combating pathological conditions associated with a cortical cholinergic deficiency, especially for the treatment of degenerative syndromes associated with senescence.
摘要:
A novel phenylethanolaminotetraline having lipolytic activity of formula ##STR1## wherin X represents hydrogen, halogen, a trifluoromethyl or a lower alkyl group and R represents hydrogen, a lower alkyl group not substituted or substituted by a cycloalkyl group containing 3 to 7 carbon atoms, a hydroxy group, a lower alkoxy, carboxy or lower carbalkoxy group; a cycloalkyl group containing 3 to 7 carbon atoms; or a lower alcanoyl group; or a pharmaceutically acceptable salt thereof; a process for its preparation; and pharmaceutical compositions containing it as active ingredient, useful for the treatment of obesity.
