标题:Derivs. of beta,beta-dimethyl-4-piperidineethanamine as inhibitors of the cholesterol biosynthesis

合成路线图解说明:

Mannich reaction between 4-isopropylpyridine (I), formaldehyde, and dimethylamine, furnished the pyridyl ethylamine (II). Subsequent hydrogenation of the pyridine ring of (III) in the presence of PtO2 gave rise to piperidine (III). This was coupled with 2-(p-chlorophenoxy)-2-methylpropionic acid (IV) to provide amide (V). Then, amide (V) reduction by means of sodium bis(methoxyethoxy)aluminum hydride produced diamine (VI). This was finally converted to the title maleate salt upon treatment with maleic acid in acetone-ether.
