실험 절차

To a mixture of 7 (3.35 g), DMAP (1.7 g) and tBuOH (5.2 g) in CH2Cl2 (50 ml) is added 3.2 g of EDCI and the clear solution is stirred over the weekend. Additional CH2Cl2 (100 ml) is added and the mixture is washed with 1N HCl (2×150 ml), sat. NaHCO3 (150 ml), brine (150 ml), dried and concentrated. This afforded 3.75 g of 8 as a pale yellow oil.
