Procedure
3,5-Difluoroaniline (4.89 g, 37 91 mM) in acetone (130 ml) and water (70 ml) at 0° C. was treated with sodium hydrogen carbonate (6.55 g, 78.0 mM) and then benzyl chloroformate (6.67 g, 5.6 ml, 39.23 mM) over 10 min. The mixture was stirred for 16 h and then poured into ice. The resultant precipitate was collected and washed with water to give the title carbamate (9.35 g, 94%);
