실험 절차

This compound was prepared from indole and methyl bromoacetate by the method described in Example 10, part i. The reaction mixture was worked up by concentrating in vacuo, diluting with water and extracting with ethyl acetate (3x). The combined extracts were washed with water (3x) and brine, dried and evaporated to an oil. The residue was purified by chromatography on flash silica eluting with petroleum spirit 40°-60° C.--diethyl ether (5:1, 2:1) to give the product.
