To a solution of 2,4-Dichloro-7H-pyrrolo[2,3-d]pyrimidine (0.056 g, 0.30 mmol) in dimethylsulfoxide (1 mL) was added DIPEA (0.12 mL, 0.60 mmol) and 6-amino-2,2-dimethyl-2H-benzo[b][1,4]oxazin-3(4H)-one (0.085 g, 0.44 mmol). After heating at 100° C. for 15 h, the mixture was diluted with ethylacetate and sequentially washed with saturated NaHCO3 and brine. The organic extracts were dried over Na2SO4 and concentrated to give 6-(2-chloro-7H-pyrrolo[2,3-d]pyrimidin-4-ylamino)-2,2-dimethyl-2H-benzo[b][1,4]oxazin-3(4H)-one (0.05 g).
