Reaction Steps

Treat a solution of (1-(trifluoromethyl)cyclopropyl)methyl 4-methylbenzenesulfonate (12 g, 40.8 mmol) in DMF (150 mL) with potassium cyanide (3.5 g, 53 mmol) and heat at 50-70° C. for 3 days. Add water, extract with EtOAc (3×), wash the combined organics with water, then brine, dry and concentrate under reduced pressure to give the title compound (2.4 g, 39%). 1H NMR (400 MHz, CDCl3): δ 2.81 (s, 2H), 1.24-1.18 (m, 2H), 0.95-0.92 (m, 2H).
