Participants

Reaction Steps

To tert-butyl (1-((2,2,2-trifluoroethyl)carbamoyl)cyclopropyl)carbamate (3.2 g, 11 mmol) in CH2Cl2 (20 mL) was added 4 M HCl in dioxane (20 mL). The solution was stirred for 18 h at ambient temperature. The reaction mixture was concentrated in vacuo and the residue placed in a 60° C. vacuum oven (24 h) to afforded the title compound as an off-white solid (2.3 g, 93%): 1H NMR (400 MHz, DMSO-d6) δ 8.77 (bs, 3H), 8.50 (t, J=6.3 Hz, 1H), 3.90 (qd, J=9.7, 6.1 Hz, 2H), 1.52-1.15 (m, 4H); 19F NMR (376 MHz, DMSO-d6) δ −70.54; 13C NMR (101 MHz, DMSO-d6) δ 175.33, 132.46 (q, J=280.8 Hz), 45.13 (q, J=34.34 Hz), 40.06, 17.57.
