Procedure

A mixture of N-[[2-(4-chlorophenyl)-3H-imidazo[4,5-b]pyridin-3-yl]acetyl]glycine ethyl ester (4.0 g, 0.0108 mole), potassium hydroxide (0.62 g, 0.011 mole), and 100 ml of 95% ethyl alcohol was heated at reflux for 2 hrs. The hot solution was filtered and allowed to cool to initiate crystallization. The solid was diluted with 95% ethyl alcohol, filtered, and washed with a little 95% ethyl alcohol. The solid was dried under high vacuum at room temperature overnight to give 2.5 g (55%) of title compound, m.p.>300° C.
