Reaction Steps

Add slowly n-BuLi (2.37 g, 36.0 mmol) to a cooled solution of diisopropylamine (3.72 g, 36.0 mmol) in 50.0 mL THF at −78° C. under nitrogen atmosphere. Stir the reaction mixture for 30 min at the same temperature, then add 4,6-dichloropyrimidine (5.0 g, 33.0 mmol) dissolved in 15 mL of THF. Stir the resultant reaction mixture for an additional 30 min at −78° C., then add cyclopropane carbaldehyde (2.58 g, 36.8 mmol). Allow the reaction mixture to warm up to room temperature. Add 50.0 mL of water and extract the organic with ethyl acetate (3×50 mL), wash with saturated aqueous sodium chloride, then dry over anhydrous sodium sulfate. Concentrate under reduced pressure under vacuum to give Cyclopropyl-(4,6-dichloro-pyrimidin-5-yl)-methanol (4.0 g, 54% yield). MS (APCI): m/z=220 [M+H]
