Procedure
Reaction of 2.5 g of t-butyl [[1-[3-(p-t-butoxyphenyl)-L-alanyl]-4-piperidinyl]oxy]acetate with 0.85 g of 5-cyano-2-picolinic acid (as in Example 1d) yields 1.55 g of t-butyl [[1-[3-(p-t-butoxyphenyl)-N-[[5-cyano-2-pyridyl]carbonyl]-L-alanyl]-4-piperidinyl)oxy]acetate. M.p. 122°-123° C. (diethyl ether/petroleum ether 4:1). MS (FAB): 565 (M+H)+.
