실험 절차

To a solution of tert-butyl 2-(8-(benzo[d]thiazol-2-yl((2-(trimethylsilyl)ethoxy)methyl)carbamoyl)-3,4-dihydroisoquinolin-2(1H)-yl)-5-(3-hydroxypropyl)thiazole-4-carboxylate (92 mg, 0.135 mmol), triphenylphosphine (35.4 mg, 0.135 mmol) and 4-iodophenol (29.7 mg, 0.135 mmol) in THF (2 mL) was added DBAD (32 mg, 0.135 mmol). The mixture was stirred at rt for 4 hours. LC/MS showed the expected product as a single peak. The mixture was diluted with EtOAc and washed with water, brine, dried over Na2SO4, and concentrated under reduced pressure. The crude material was purified by column chromatography on silica gel eluting with 3% EtOAc in hexanes to provide 110 mg (92%) of the desired product: 1H NMR (300 MHz, CDCl3) δ ppm 8.30 (1H, m), 7.72 (1H, d), 7.54 (4H, m), 7.34 (3H, m), 6.67 (2H, d), 6.00 (2H, s), 5.14 (2H, s), 3.96 (4H, m), 3.75 (2H, t), 3.22 (2H, t), 3.06 (2H, t), 2.13 (2H, m), 1.59 (9H, s), 0.97 (2H, t), 0.01 (9H, m). MS (ESI(+)): m/z 833 (M+H).
