Reaction Steps

To a solution of 4,6-dichloro-2-(methylthio)-5-nitropyrimidine (327 mg, 1.36 mmol) in THF (5.4 mL) at −10° C. was added Et3N (474 μL, 3.40 mmol) followed by a solution of NH3 (2.0 M in MeOH, 750 μL, 1.5 mmol). The mixture was stirred while warming to 0° C. for 1.5 h (LC/MS indicated consumption of starting materials.). The reaction mixture was taken forward without work-up.
