Reaction Steps

A mixture of 100 mg (1.3 mmol) of n-butanol, 400 mg (3.6 mmol) of potassium tert. butoxide and DMF was heated at 80 degree C. for 5 minutes. 300 mg (0.65 mmol) of 2-ethyl-sulfonyl-7-methyl-3[(2'-(1H-tetrazol-5-yl)biphenyl-4-yl)methyl]-3H-imidazo[4.5-b]pyridine was added to the mixture. The resultant was heated for 2 hours. The reaction product mixture was mixed with water, neutralized with 2n HCl and extracted with dichloromethane. The dichloromethane phase was washed with a saturated saline and dried with anhydrous magnesium sulfate. The solvent was distilled out at a reduced pressure and the residue was treated with ether hexane-dichloromethane or re-crystallization to obtained 140 mg of the intended compound.
