실험 절차

A mixture of 2-(4-(methylsulfonamido)-1,3-dioxoisoindolin-2-yl)acetic acid (78 mg, 0.262 mmol), (S)-3,5-dichloro-4-(2-(3-(cyclopropylmethoxy)-4-(difluoromethoxy)-phenyl)-2-hydroxyethyl)pyridine 1-oxide (110 mg, 0.262 mmol), DMAP (15.97 mg, 0.131 mmol) and EDC (125 mg, 0.654 mmol) in 15 ml of THF was stirred at room temperature for 2 days. The mixture was diluted with water, acidified and extracted twice with EtOAc; the organic layer was then washed with brine, dried over sodium sulfate and evaporated. The residue was triturated with methanol and the title compound was obtained as a pale yellow solid (39 mg, 0.056 mmol, 21.29% yield, MS/ESI+ 700.11 [MH]+, [αD]=−63.94, c=0.355 in DCM). 1H NMR (300 MHz, DMSO-d6) δ ppm 9.29 (br. s., 1H), 8.47 (s, 2H), 7.86 (dd, 1H), 7.81 (dd, 1H), 7.63 (dd, 1H), 7.19 (d, 1H), 7.10 (d, 1H), 6.97 (dd, 1H), 7.08 (t, 1H), 6.02 (dd, 1H), 4.46 (d, 1H), 4.38 (d, 1H), 3.93 (d, 2H), 3.41 (dd, 1H), 3.30 (s, 3H), 3.24 (dd, 1H), 1.10-1.31 (m, 1H), 0.48-0.66 (m, 2H), 0.27-0.48 (m, 2H)
