Reaction Conditions

Reaction Steps

In 50 ml of dichloromethane, 300 mg (0.52 mmol) of [9-(4-{3-[4-(2-hydroxyethyl)-3-(trifluoromethyl)phenyl]-ureido}phenyl)-9H-purin-6-yl]-methyl-carbamic acid tert-butyl ester was dissolved, and 270 mg (0.64 mmol) of Dess-Martin periodinane was added thereto under cooling with ice and the solution was stirred at 0° C. for 20 hours. The reaction solution was partitioned between water and ethyl acetate and the organic layer was washed with a saturated sodium chloride solution and concentrated under reduced pressure. The product was purified by a silica gel column (ethyl acetate) to obtain 140 mg (47%) of a target product as a colorless amorphous substance.
