Reaction Steps

Nitrogen was passed through a solution containing 1.39 g. methyl 3-methoxy-4-(6-nitroindol-1-ylmethyl)benzoate in 1:1 v/v methanol and THF together with 0.86 g. lithium hydroxide monohydrate in 25 ml. water. After 1 minute the reaction mixture was sealed and stirred for 3 days. Solvent was then evaporated. The residue was diluted with water, acidified (1M hydrochloric acid) and extracted with ethyl acetate. The extracts were washed with water, then with brine and were dried (MgSO4). Evaporation of solvent gave a 3-methoxy-4-[6-nitroindol-1-ylmethyl]benzoic acid in 91% yield as a solid m.p. 243°-245.5° C. which was used without further purification.
