PROCEDURE

实验过程

To a solution of 7 (152.2 mg, 0.2 mmol), Pd(PPh3)4 (23.2 mg, 0.02 mmol) in dry methanol (6 mL) under argon was added morpholine (35 μL, 0.40 mmol) which was allowed to stir for 2 h. The reaction mixture was concentrated in vacuo, purification by column chromatography on silica (eluent 0:1-5:95-10:90-10:90+0.5% AcOH MeOH/CH2Cl2) to give a yellow solid 8 (137 mg, 0.18 mmol, 100%): Rf 0.19 MeOH/CH2Cl2 (1:9+0.5% AcOH); IR (thin film) 3271 (b), 2962 (m), 2926 (m), 1624 (s), 1536 (m) cm−1.
