Procedure
30 g of the 3-(imidazo[4,5-b]pyridine-2-ylthio)-3-(4-chlorobenzoyl)propionic acid hydrobromide obtained above are dissolved in a dilute NaHCO3 solution (25 g NaHCO3 in 800 ml water), and the solution is filtered and the filtrate acidified with acetic acid. The solid is collected, washed well with water and air dried, yielding 20 g of material. The solid is recrystallized from hot acetonitrile. The title compound decomposes at about 140° C.
