Summary: | The present inventors found a novel method for reducing formyl groups with the use of a Lewis acid and a hydride reducing agent in a production method for a 3-methyl-4-haloindole derivative. The present inventors also found that demethylation and/or dehalogenation of the derivative are suppressed by this method, making post-treatment easier or the derivative obtained at a high yield. |
