YieldReaction ConditionsOperation in experiment
90% With triphenylphosphine; diethylazodicarboxylate; In dichloromethane; at 20℃; Methyl 5-Hydroxy-1 /-/-indole-2-carboxylate (0.10 g, 0.5 mmol), triphenylphosphine (0.28 g, 1.0 mmol), diethyl azodicarboxylate (0.18 g, 1.0 mmol) and (2,2-dimethyl- 1 ,3-dioxan-5-yl)methanol (0.15 g, 1.0 mmol) were dissolved in CH2CI2 (5 ml.) and the mixture was stirred overnight. The solvent was evaporated. Purification was accomplished by Reverse-Phase HPLC (water/acetonitrile with 0.1percentTFA). The desired fractions were neutralized with saturated NaHCObeta and extracted with EtOAc. The organic extracts were combined dried over Na2SO4, filtered and evaporated to afford the title compound (0.15 g, 90percent) as a tan solid. 1H NMR (400 MHz, DMSO-c/6): delta ppm 1 1.74 (br. s., 1 H), 7.29 (d, 1 H), 7.09 (d, 1 H), 7.01 (d, 1 H), 6.88 (dd, 1 H), 3.92 - 4.01 (m, 4 H), 3.81 (s, 3 H), 3.72 (dd, 2 H), 1.97 - 2.08 (m, 1 H), 1.31 (s, 3 H), 1.28 (s, 3 H). MS: m/z 342.2 (M+23).
