摘要:
The present invention provides processes useful for preparing 5-lipoxygenase activating protein (FLAP) inhibitors and their intermediates. In particular, processes for preparing 3-[3-(tert-butylsulfanyl)-1-[4-(6-ethoxy-pyridin-3-yl)benzyl]-5-(5-methyl-pyridin-2-yl-methoxy)-1H-indol-2-yl]-2,2-dimethyl-propionic acid, the anhydrous Form C polymorph of sodium 3-[3-(tert-butylsulfanyl)-1-[4-(6-ethoxy-pyridin-3-yl)benzyl]-5-(5-methyl-pyridin-2-yl-methoxy)-1H-indol-2-yl]-2,2-dimethyl-propionate, and intermediates useful in said processes are provided.
摘要:
A process for preparing purine derivatives, such as famiciclovir and penciclovir, by reacting, in the presence of a palladium (0) catalyst and a ligand, a compound of the formula with a compound of the formula wherein X is H, OH or halo; Y is a leaving group; and R1 and R2 are selected independently from C1-12alkyl, aryl, C1-12alkylaryl, C1-12alkylsilyl, arylsilyl and C1-12alkyldiarylsilyl or are joined together to form a moiety of the formula wherein R3 and R4 are selected independently from H, C1-12alkyl and aryl.
