Procedure

To a solution of 2-methyl-2-phenoxypropanamide from Step C (0.01 mol) in dry CH2Cl2 (50 mL) and triethylamine (3.03 g, 0.03 mol) at 0° C. was added trifluoroacetic anhydride (3.15 g, 0.015 mol). After the addition was complete, the solution was allowed to warm to room temperature and stirring was continued at ambient temperature overnight. The reaction mixture was then refluxed for 3 hours. After cooling to room temperature and dilution with CH2Cl2 (100 mL), the solution was washed with saturated aqueous NaHCO3 (50 mL×3), water, and brine and dried over sodium sulfated. Evaporation gave the titled compound. 1H NMR (400 MHz, CDCl3) δ ppm 7.32˜7.36 (m, 2H), 7.14˜7.20 (m, 3H), 1.71 (s, 6H).
