실험 절차

To a solution of triphenyl phosphine (0.63 g, 2.4 mmol) in THF (10 mL) was added DIAD (0.47 mL, 2.4 mmol) at 0° C. After 10 min, (1R)-cyclopropanecarboxylic acid {2-[1-(3-ethoxy-4-methoxy-phenyl)-3-hydroxy-propyl]-3-oxo-2,3-dihydro-1H-isoindol-4-yl}-amide (0.93 mL, 2.2 mmol) was added as solid. After 5 min, sodium thiomethoxide (180 mg, 2.6 mmol) was added. After 20 min, the cold bath was removed and the mixture was stirred at room temperature for 1.5 hrs. To the mixture was added water (15 mL), methanol (15 mL), and oxone (5.4 g, 8.8 mmol) and kept for 16 h. The mixture was extracted with methylene chloride (100 mL) and water (50 mL). The organic layer was dried over MgSO4. The solvent was removed in vacuo to give a solid. The solid was purified with prep HPLC to give (1R)-cyclopropanecarboxylic acid {2-[1-(3-ethoxy-4-methoxy-phenyl)-3-methanesulfonyl-propyl]-3-oxo-2,3-dihydro-1H-isoindol-4-yl}-amide as a white solid (50 mg, 5% yield): mp, 148-150° C.; 1H NMR (CDCl3) δ 0.89-0.94 (m, 2H, CH2), 1.10-1.13 (m, 2H, CH2), 1.46 (t, J=7 Hz, 3H, CH3), 1.65-1.73 (m, 1H, CH), 2.60-2.69 (m, 2H, CH2), 2.96 (s, 3H, CH3), 3.02-3.22 (m, 2H, CH2), 3.87 (s, 3H, CH3), 3.99 (d, J=17 Hz, 1H, NCHH), 4.07 (q, J=7 Hz, 2H, CH2), 4.30 (d, J=17 Hz, 1H, NCHH), 5.48 (t, J=8 Hz, 1H, NCH), 6.84-7.02 (m, 4H, Ar), 7.46 (t, J=8 Hz, 1H, Ar), 8.45 (d, J=8 Hz, 1H, Ar), 10.49 (s, 1H, NH); 3C NMR (CDCl3) δ 8.30, 14.75, 16.19, 23.78, 41.24, 45.95, 51.99, 53.01, 56.00, 64.65, 111.60, 112.37, 116.88, 117.00, 117.89, 119.46, 129.82, 133.52, 138.09, 141.29, 148.87, 149.55, 169.79, 172.66; Anal Calcd for C25H30N2O6S1: C, 61.71; H, 6.21; N, 5.76. Found: C, 61.33; H, 6.19; N, 5.59.
