Reaction Steps
To neat 5-Cyano-2-ethyl-7-methyl-3-(2'-(tetrazol-5-yl)biphen-4-yl)methyl-3H-imidazo[4,5-b]pyridine (20 mg) at RT was added H2SO4 (0.5 mL) and water (0.25 mL). The mixture was heated to 100° C. for 3 hours, cooled to 0° C., then made basic by the addition of NH4OH. After adding methanol (5 mL), the mixture was filtered, concentrated, and purified (SiO2, 60:40:1 CH2Cl2 --CH3OH--NH4OH) to give 17 mg of the title compound as a solid.
