实验步骤: RuPhospalladium(II)phenethylaminechloride (2.83 mg, 0.00388 mmol), 2-dicyclohexylphosphino-2′,6′-di-i-propoxy-1,1′-biphenyl (1.81 mg, 0.00388 mmol), 4-(4-chlorophenyl)-2-iodo-4,5,6,7-tetrahydro-8H-thieno[2,3-c]azepin-8-one (31.3 mg, 0.0776 mmol), (2S)-morpholin-2-ylmethanol (16.0 mg, 0.137 mmol), and tetrahydrofuran (0.63 mL) were combined in a rbf equipped with a stirbar. The flask was sealed with a septum then evacuated and refilled with argon three times. To this solution was added a solution of lithium bis(trimethylsilyl)amide) in tetrahydrofuran (1.0 M, 0.31 mL, 0.31 mmol). The sealed r×n was vigorously stirred @ 40° C. for 19 hr. The reaction was cooled to rt, quenched into saline, extracted into EA, washed with saline, dried over Na2SO4, filtered, and concentrated in vacuo. The crude oil was purified using column chromatography on silica gel (24 g ISCO column, gradient 100% DCM to 100% EA over 50 minutes; after unreacted starting material and dehalogenated starting material eluted, the eluant was switched to 5% MeOH in EA) to give the title compound (4.8 mg, 16%) as a mixture of diastereomers. LCMS: (FA) ES+ 393, 395. 1H NMR (400 MHz, DMSO) δ 7.78 (t, J=4.6 Hz, 1H), 7.38-7.35 (m, 2H), 7.15-7.11 (m, 2H), 5.59 (s, 1H), 4.80-4.75 (m, 1H), 4.34-4.31 (m, 1H), 3.91-3.79 (m, 1H), 3.61-3.35 (m, 6H), 3.24 (d, J=11.9 Hz, 1H), 3.11-3.07 (m, 2H), 2.81-2.69 (m, 1H), 2.22-2.14 (m, 1H), 2.02-1.88 (m, 1H).
