Reaction Steps

To a solution of 1-{4-[1-(cyclopropylmethyl)-4-(methylsulfanyl)-1H-benzotriazol-5-yl]-2-fluorobenzyl}-3-methylimidazolidine-2,4-dione (Example 15, 14 mg, 0.032 mmol) in chloroform (0.45 mL) at 0° C. was added meta-peroxychlorobenzoic acid (7.1 mg, 0.032 mmol). The mixture was stirred for 1.5 hours at 0° C. and then warmed to ambient temperature and stirred for an additional 14 hours. The mixture was cooled to 0° C. and treated with calcium hydroxide (3.3 mg, 0.045 mmol), stirred for 30 minutes and filtered. The filtrate was concentrated in vacuo and purified via preparative reversed-phase HPLC (5-95% MeCN/water+0.1% TFA) to provide the title compound: 1H NMR (400 MHz, CDCl3) 7.82 (d, 1H, J=8.0 Hz), 7.42 (d, 1H, J=8.8 Hz), 7.39 (t, 1H, J=7.6 Hz), 7.17-7.23 (m, 2H), 4.70 (s, 2H), 4.61 (d, 2H, J=7.2 Hz), 3.89 (s, 2H), 3.67 (s, 3H), 3.06 (s, 3H), 1.41-1.47 (m, 1H), 0.71-0.76 (m, 2H), 0.54-0.58 (m, 2H) ppm. LRMS m/z (M+H) 472.2 found, 472.1 required.
