To a solution of (2-chloropyrimidin-4-yl)(cyclopropyl)methanone (175 mg, 0.958 mmol) in THF (3 mL) at −78° C. under a nitrogen atmosphere was added methyl magnesium chloride (3.0 M in diethyl ether, 0.380 mL, 1.15 mmol) dropwise. The solution was warmed to room temperature and stirred for an additional 30 min. The solution was diluted with EtOAc, washed with brine, dried with MgSO4, filtered, and concentrated to dryness to afford 1-(2-chloropyrimidin-4-yl)-1-cyclopropylethanol (115 mg, 0.579 mmol, 60% yield). MS ESI: [M+H]+ m/z 199.1. 1H NMR (500 MHz, CDCl3) δ 8.60 (d, J=5.2, 1H), 7.43 (d, J=5.2, 1H), 3.43 (s, 1H), 1.52 (s, 3H), 1.26 (m, 1H), 0.60 (m, 1H), 0.50 (m, 1H), 0.40 (m, 1H), 0.30 (m, 1H).
