A mixture of 2,4,6-trichloro-5-methoxy-pyrimidine (1 g, 4.68 mmol), morpholin-3-yl-methanol hydrochloride (0.86 g, 5.6 mmol) and triethylamine (0.9 mL, 6.5 mmol) in IMS (30 mL) was stirred at RT for 3 h, then concentrated in vacuo. The resulting residue was purified by column chromatography (SiO2, 0 to 50% ethyl acetate in cyclohexane) affording [4-(2,6-Dichloro-5-methoxy-pyrimidin-4-yl)-morpholin-3-yl]-methanol (614 mg, 45%). LCMS (method A): RT=2.63 min, [M+H]+=294/296.
