Participants

Reaction Steps

A mixture of 571 mg of 1-[2-(4-chloro-2,5-difluorophenyl)-6,6-dioxido-5,7-dihydrothieno[3,4-d]pyrimidin-4-yl]piperidin-4-ol, 0.30 g of 4-nitrophenyl chloroformate, 0.12 ml of pyridine, and 10 ml of methylene chloride was stirred at ambient temperature for 17 hours. Saturated aqueous ammonium chloride solution was added to the reaction mixture, and the mixture was extracted twice with chloroform. The organic phase was washed with brine, dried over anhydrous magnesium sulfate, and evaporated under reduced pressure to yield 894 mg of 1-[2-(4-chloro-2,5-difluorophenyl)-6,6-dioxido-5,7-dihydrothieno[3,4-d]pyrimidin-4-yl]piperidin-4-yl 4-nitrophenyl carbonate as light yellow solid.
