Reaction Conditions

Reaction Steps

2,4-dichloro-6-[(phenylsulfonyl)methyl]pyrimidine (2.8 g, 9.24 mmol) was dissolved in DCM (20 mL) and stirred (under nitrogen) at −5° C. Triethylamine (1.42 mL, 10.17 mmol) was added to give a clear brown solution. (3S)-3-methylmorpholine (935 mg, 9.24 mmol) was dissolved in DCM and added dropwise keeping the reaction below −5° C. The cooling bath was then removed and the reaction mixture stirred at room temperature for 1 hour. The reaction mixture was then washed with water (50 mL), dried over magnesium sulphate, filtered and concentrated in vacuo. The crude material was chromatographed on silica, eluting with 0-50% ethyl acetate in DCM to give the desired material as a white solid (2.6 g).
