Procedimiento

The compound obtained in Example 62 (1.0 g) is treated in the same manner as in Example 64 with using propionyl chloride (0.23 g) instead of acetic anhydride to give ethyl 2-n-propyl-5-propionyl-3-[2'-(t-butoxycarbonyl)biphenyl-4-yl]methyl-4,5,6,7-tetrahydroimidazo[4,5-c]pyridine-4-carboxylate (0.82 g) as a white foam.
