Procedure
A solution of 0.79 g of chloroacetonitrile in 5 ml of DMF is added dropwise at 20°, with stirring, to a solution of 3.82 g of 2-butyl-3-(2'-cyanobiphenyl-4-ylmethyl)-4,5-dihydro-4-oxo-3H-imidazo[4,5-c]pyridine and 1.17 g of potassium tert-butylate in 20 ml of DMF. The mixture is stirred at 20° for a further 30 min and poured on to ice, hydrochloric acid is added to pH 6 and the mixture is worked up in conventional manner to give 2-butyl-3-(2'-cyanobiphenyl-4-ylmethyl)-5-cyanomethyl-4,5-dihydro-4-oxo-3H-imidazo[4,5-c]pyridine, m.p. 64°.
