Water → HCID 49758603, compound

A solution of cyanuric chloride (3.69 g, 20 mmol) in dry THF (20 mL) under nitrogen was treated dropwise with a solution of 3-methoxyphenylmagnesium bromide in THF (20 mL, 1M, 20 mmol). The solution became warm and was stirred for 30 minutes at room temperature followed by stirring overnight at ˜40° C. The reaction was poured into a mixture of saturated sodium bicarbonate (50 mL) and water (50 mL) forming a solid. The mixture was stirred for 20 minutes and separated layers. The aqueous layer was extracted with ethyl acetate (EtOAc) twice. The combined organic layers was dried over magnesium sulfate, filtered and concentrated on a rotary evaporator to yield a tan solid. The solid was dissolved in chloroform and loaded onto 100 g of silica gel. The silica gel was eluted with 10% ethyl acetate/hexanes followed by 20% ethyl acetate/hexanes. The appropriate fractions were concentrated on a rotary evaporator to yield 2,4-dichloro-6-(3-methoxyphenyl)-1,3,5-triazine (VIII) as a white solid (0.52 g, 4.50 g). ESI/MS 256.1, 258.1, 260.1 (M+H).
