Procedure

Under an inert atmosphere, a solution of 3 g of N-(2-hydroxyphenyl)-1H-indol-4-carboxamide and 1.65 g of potassium carbonate in 100 ml of acetone was refluxed for 24 hours with 4.7 ml of epichlorhydrin and after purifying by chromatography over silica (eluent: ethyl acetate--triethylamine, 9-1) and evaporating to dryness, the residue was triturated in pentane, then filtered and dried under reduced pressure at 60° C. to obtain 2.8 g of N-[2-[(2-oxiranyl)methoxy]phenyl]-1H-indol-4-carboxamide melting at 122° C.
