Participants

Reaction Steps

To a stirred solution of (1S,2R)-3,3-difluorocyclohexane-1,2-diaminium bis(trifluoroacetate) (7.5 g, 19.8 mmol) in dichloromethane (100 mL) was added triethylamine (11.1 mL, 79.0 mmol) followed by BOC2O (5.52 mL, 23.8 mmol). The reaction was stirred for 10 hr at ambient temperature. Concentrated, and purified by flash chromatography to afford the title compound. 1H NMR (CDCl3, 500 MHz) 4.76 (br s, 1H); 3.39 (m, 1H); 2.71-2.64 (m, 1H); 2.2-2.1 (m, 2H); 1.7-1.59 (m, 2H); 1.56-1.51 (m, 2H); 1.45 (s, 9H); 1.29-1.21 (m, 2H). 19F NMR (CDCl3, 564 MHz) −100.4-−100.9 (d, 1F); −114.35-−114.87 (d, 1F).
