The synthesis of αMT can be accomplished through several different routes, the two most widely known being the nitroaldol condensation between indole-3-carboxaldehyde and nitroethane under ammonium acetate catalysis which produces 1-(3-indolyl)-2-nitropropene-1, the product can subsequently be reduced using a reducing agent like lithium aluminum hydride[1] The alternative synthesis is the condensation between indole-3-acetone and hydroxylamine.[citation needed], followed by reduction of the obtained ketoxime with lithium aluminum hydride.[2]
