Reaction Steps

A pressure reactor was charged with 4-nitro-3-trifluoromethyl-N-[2,3-epoxy-2-methyl propionyl]aniline, BP-33, (10.0 g, 34.46 mmol) (see FIG. 3) and methanol (100 mL). After cooling to −70° C., ammonia in excess was condensed into the reactor which was sealed and stirred 14 hours. Following evaporation, the crude solid was washed with cold CH2Cl2 (50 mL). Filtration and drying gave 6.1 g BP-34 (58% yield).
