Reaction Steps

To a solution of (S)-3,5-dichloro-4-(2-(3-(cyclopropylmethoxy)-4-(difluoromethoxy)phenyl)-2-hydroxyethyl)pyridine 1-oxide (180 mg, 0.428 mmol), DMAP (52.3 mg, 0.428 mmol) and EDC (164 mg, 0.857 mmol) in DCM (10 ml), 2-(5-(N-(2-(dimethylamino)ethyl)methylsulfonamido)-1,3-dioxoisoindolin-2-yl)acetic acid hydrochloride (191 mg, 0.471 mmol) was added portion wise within 4 hours, and the reaction was stirred at room temperature for 24 hours. The solvent was evaporated and the crude was purified by flash silica gel chromatography (DCM/MeOH 10/0.2) affording (S)-3,5-dichloro-4-(2-(3-(cyclopropylmethoxy)-4-(difluoromethoxy)phenyl)-2-(2-(5-(N-(2-(dimethylamino)ethyl)methylsulfonamido)-1,3-dioxoisoindolin-2-yl)acetoxy)ethyl)pyridine 1-oxide as a white solid (253 mg, 0.328 mmol, 77% yield). MS/ESI+ 771.15 [MH]+, [αD]=−32.18, c=0.353, DCM). 1H NMR (300 MHz, DMSO-d6) δ ppm 8.43 (s, 2H), 7.93-8.00 (m, 2H), 7.89 (dd, 1H), 7.19 (d, 1H), 7.09 (d, 1H), 6.97 (dd, 1H), 7.08 (t, 1H), 6.02 (dd, 1H), 4.43 (s, 2H), 3.92-4.05 (m, 2H), 3.88 (t, 2H), 3.39 (dd, 1H), 3.23 (dd, 1H), 3.13 (s, 3H), 2.31 (t, 2H), 2.10 (s, 6H), 1.07-1.33 (m, 1H), 0.49-0.71 (m, 2H), 0.27-0.49 (m, 2H)
