Reaction Steps

4-Fluoro-3-(trifluoromethylsulfonyl)benzenesulfonamide (1.536 g, 5 mmol), 2-methoxyethanamine (0.376 g, 5 mmol), and triethylamine (1.939 g, 15 mmol) in anhydrous tetrahydrofuran (30 mL) solution was heated at 55° C. for 3 hours. The solution was diluted with ethyl acetate, washed with water and brine, and dried (Na2SO4), filtered and the filtrate was concentrated. The crude material was used in the next step without further purification.
