Reaction Steps

Treat a solution of (1-(trifluoromethyl)cyclopropyl)methanol (7 g, 50 mmol) and p-toluenesulfonyl chloride (10.4 g, 55 mmol) in DCM (100 mL) with TEA (10 g, 100 mmol) and 4-dimethylaminopyridine (DMAP) (0.6 g, 5 mmol) and stir at RT overnight. Wash successively with 2 M HCl, satd. NaHCO3, and brine, dry over Na2SO4 and concentrate to give the title compound (12 g, 81%). 1H NMR (400 MHz, DMSO-d6): δ 7.79 (d, J=8.0 Hz, 2H), 7.50 (d, J=8.0 Hz, 2H), 4.13 (s, 2H), 2.43 (s, 3H), 1.08-1.05 (m, 2H), 0.96-0.94 (m, 2H).
