Reaction Steps

A mixture of 8 ml of an aqueous 10% sodium hydroxide solution of 500 mg (1.3 mmol) of 2-hydroxymethyl-3-[(2'-methoxycarbonyl-biphenyl-4-yl)methyl]-7-methyl- 3H-imidazo[4.5-b]pyridine and 20 ml of ethanol was heated for reflux for 2 hours. The insoluble was removed out and the filtrate was concentrated. The residue was mixed with water and washed with ethyl acetate.
