실험 절차

A solution of 7.52 g (26.6 mmol) of the product from step C in 50 ml of CH2Cl2 and 80 ml of anhydrous pyridine was treated with 11.12 g of (methoxycarbonylsulfamoyl)-triethylammonium hydroxide inner salt (Burgess reagent) in 1-g portions over 5 min. After stirring for 1.5 hr, TLC (90-10-1, CHCl3 -CH3OH-H2O) showed complete conversion to product, and the solution was evaporated to give a paste, to which H2O was added, up to 400 ml, with trituration and stirring to afford, after standing 20 hr at 0° C., filtration and drying in vacuo, the title compound as a white solid.
