PROCEDURE

实验过程

A solution of 8.5 g of the product of Stage B and 2.4 ml of triethylamine in 100 ml of dichloromethane was saturated with methanethiol by sweeping through the stirred solution cooled to -20° C. The temperature was allowed to rise and then the solution was maintained under a nitrogen pressure of 10 bars at 40° C. for 48 hours. After concentration, the residue was purified by chromatography on silica (eluant: dichloromethane-MeOH 20-1) to obtain 8.0 g of the expected product with an Rf (SiO2, dichloromethane-MeOH20-1)=0.39.
