反応条件: temp:0.00; pressure:0.00; stir:

反応条件: temp:60.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: 2-(2,2,2-Trifluoroethyl)oxirane (5.27 g, 41.8 mmol) was added to a solution of ammonia (2 M in methanol; 170 mL, 340 mmol) and the solution heated to 60° C. After 1.25 h, the mixture was allowed to cool to ambient temperature and concentrated to a volume of 20 mL. HCl (4 M in dioxane; 12 mL, 48 mmol) was added slowly and the mixture concentrated to give a white solid (4.0 g) that was 85% pure and contained 15% of a dimeric byproduct. MS 144.1 (M+H). 1H NMR (500 MHz, CD3OD) δ 4.17-4.12 (m, 1H), 3.10 (dd, J=12.9, 2.9 Hz, 1H), 2.89 (dd, J=12.7, 9.8 Hz, 1H), 2.50, 2.35 (m, 2H). to cool to ambient temperature concentrated to a volume of 20 mL the mixture concentrated
