실험 절차

Under an atmosphere of argon, 5.00 g (27.9 mmol) of 4-nitro-1H-pyrrolo[2,3-b]pyridine 7-oxide and 11.8 ml (55.8 mmol) of hexamethyldisilazane are initially charged in 290 ml of THF. At RT, 10.8 ml (140 mmol) of methyl chloroformate are added. The solution is stirred at RT overnight. The reaction solution is filtered through a silica gel cartridge, and the cartridge is washed with dichloromethane/methanol 10:1.
