Reaction Conditions

Reaction Steps

2,4-Dichloro-6-[(isopropylsulfonyl)methyl]pyrimidine (2.65 g, 9.85 mmol) was dissolved in DCM (50 mL) and stirred (under nitrogen) at −5° C. Triethylamine (1.5 mL, 10.84 mmol) was added to give a clear brown solution. Morpholine (0.86 mL, 9.85 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 (2.5 g).
