Reaction Steps

A mixture of 3-(trans-4-acetoxycyclohexyl)-1-(3,4-dimethoxybenzyl)-6-trifluoromethyl-2,3-dihydro-1H-imidazo[4,5-b]pyridin-2-one (125 mg) in a mixture of tetrahydrofuran (1 mL), methanol (0.5 mL) and 1N-sodium hydroxide (0.507 mL) was refluxed for an hour. After cooling to room temperature, the mixture was concentrated in vacuo. Water was added to the residue, and the resulting precipitate was collected by filtration. The obtained solid was washed with water and subjected to a preparative silica gel column chromatography eluting with 5% methanol in chloroform. The obtained solid was washed with a mixture of diethyl ether and diisopropyl ether to give 1-(3,4-dimethoxybenzyl)-3-(trans-4-hydroxycyclohexyl)-6-trifluoromethyl-2,3-dihydro-1H-imidazo[4,5-b]pyridin-2-one (62.9 mg) as a colorless solid.
