A process for the preparation of 1-benzyl-4-[(5,6-dimethoxy-1-indanon)-2-yl] methyl piperidine hydrochloride (Donepezil HCl) is disclosed. 5,6-Dimethoxy-2-(pyridin-4-yl) methylene inda-1-one is hydrogenated with a noble metal catalyst or a non-oxide derivative of a noble metal catalyst in a solvent at 20-100° C. and 10-90 psi gauge pressure. The resulting 4-[(5,6-dimethoxy-1-indanon)-2-yl] methyl piperidine is alkylated with an alkylating agent in an organic solvent at 20-80° C.
This invention relates to compounds of the formula
wherein Q, Z, D, E, R3, R4, R5 and R6 are defined as below, and the pharmaceutically acceptable salts thereof are disclosed. The compounds are useful as antihypertensive agents.
