Reaction Steps

A mixture of 1.9 g (6.456 mmol) of [4-cyclopropyl-2-(4-trifluoromethyl-phenyl)-pyrimidin-5-yl]-methanol and 0.515 ml (7.1 mmol) thionylchloride in 20 ml dichloromethane was stirred for 1 h at RT. The reaction mixture was taken up in ether and washed with sodium bicarbonate solution and water. The ether phase was concentrated under reduced pressure to give 1.97 g of pure 5-chloromethyl-4-cyclopropyl-2-(4-trifluoromethyl-phenyl)-pyrimidine.
