실험 절차

N-(2,2-dimethyl-3-oxo-3,4-dihydro-2H-1,4-benzoxazin-7-yl)-N-(methylsulfonyl)methanesulfonamide (7.50 g), 4-fluorophenylboronic acid (5.27 g), 4-dimethylaminopyridine (0.53 g), tributylamine (3.20 g) and copper(II) acetate monohydrate (0.43 g) were added to dimethylsulfoxide (56 mL), and the mixture was stirred at 20° C. for 26 hours under blowing air (7 to 10 mL/min) thereto. The reaction mixture was added dropwise to a mixed solution of dimethylsulfoxide/concentrated hydrochloric acid/water (19 mL/4.5 g/34 mL) at about 15° C., and washed with dimethylsulfoxide (7.5 mL). The mixture was stirred at 10° C. for 3 hours, then the precipitated crystals were successively washed with dimethylsulfoxide/water (12 mL/3 mL) and water (75 mL), and then dried to obtain the title compound (9.09 g) as white crystals (yield: 95%, purity: 92%).
