N-Methylmorpholine (0.007 ml, 0.062 mmol) was added dropwise to solution of 4-nitrophenyl chloroformate (12.5 mg, 0.062 mmol) in dichloromethane (1 ml) with stirring under nitrogen at 0° C. After 20 minutes, the ice-water bath was removed and the mixture was allowed to warm up to ambient temperature. 3-[4-amino-5-(4-phenoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidin-7-yl]cyclopentanol (20 mg, 0.052 mmol) was added to the mixture and the resulting solution was stirred for 24 hours. The reaction mixture was diluted with dichloromethane and washed with water, saturated sodium bicarbonate, and brine. The organic layer was dried (MgSO4), filtered and evaporated to give 3-[4-amino-5-(4-phenoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidin-7-yl]cyclopentyl (4-nitrophenyl) carbonate. The structure was confirmed by 1H NMR.
