Participants

Reaction Steps

In anhydrous tetrahydrofuran was dissolved 6.9 g of the compound obtained in step (c) above, and 3 g of triethylamine and then 3.3 g of ethyl chlorocarbonate were added to the solution at 0° C. The mixture was stirred for 20 minutes. Into the liquid reaction mixture was dropped 3.1 g of morpholine at 0° C., and the mixture was stirred for 30 minutes. The liquid reaction mixture was extracted with n-hexane, and the extract was washed with water and dried. The solvent was removed by distillation and the residue was purified by column chromatography using silica gel to obtain 5.6 g of the intended compound in the form of an oil.
