実験手順

Triethylamine (0.101 g, 0.1 mmol) was added to a solution of 1a (0.684 g, 3 mmol) and 24a (0.33 g, 3 mmol) in dry THF (5 ml). The reaction mixture was stirred at room temperature for 5 h and then concentrated to yield a brown residue which was subjected to flash chromatography (dichloromethane/acetone, 93:7) to afford 24b (0.741 g, 2.19 mmol, 73%).
