2-(2,4-Dichloro-6-morpholin-4-yl-pyrimidin-5-yloxy)-N-methoxy-N-ethyl-acetamide → 1-(2,4-Dichloro-6-morpholin-4-yl-pyrimidin-5-yloxy)-propan-2-one

Participants

Reaction Steps

To a solution of 2-(2,4-dichloro-6-morpholin-4-yl-pyrimidin-5-yloxy)-N-methoxy-N-ethyl-acetamide (200 mg, 0.60 mmol) in THF (4 mL) at −78° C. was added methylmagnesium bromide (1.28 mL, 1.79 mmol, 1.4 M solution in THF/toluene) and the resulting mixture warmed to RT and stirred for 3 hours. The resulting mixture was quenched with 1M HCl and extracted with ethyl acetate. The combined organic extracts were washed with brine, then dried (Na2SO4) and concentrated in vacuo affording 1-(2,4-Dichloro-6-morpholin-4-yl-pyrimidin-5-yloxy)-propan-2-one as a white solid (146 mg, 80%). LCMS: RT=2.90 min, [M+H]+=306/308/310.
