실험 절차

To a 0° C. solution, under argon, of 0.821 g of product from Example 56 and 3.4 ml of pyridine is added 148 microliter of methanesulfonyl chloride. The reaction is stirred at 0° C. for 2 hours, diluted with water and extracted with chloroform. The organic layer washed with water and saturated sodium chloride, dried and concentrated in vacuo. The residue is purified by chromatography (Silica Gel; 80% ethyl acetate/hexane) to give 0.632 g of the desired product.
