Racemic CP-690550 can be obtained by the following method. Reductive amination of 1-benzyl-4-methylpiperidin-3-one (I) with methylamine and sodium triacetoxyborohydride in THF gives N-methyl-1-benzyl-4-methylpiperidin-3-amine (II), which is condensed with 4-chloro-7H-pyrrolo[2,3-d]pyrimidine (III) by means of triethylamine in a sealed tube at 100 °C to yield the tertiary amine (IV). After deprotection of (IV) by catalytic hydrogenolysis over Pd(OH)2/C, the debenzylated piperidine (V) is acylated with cyanoacetyl chloride (VI) and pyridine in CH2Cl2 to provide the target compound (1). Scheme 1.
