Summary: | 3-(1-Hydroxy-4-chlorobenzyl)-1-methylindole (3) has been synthesised in three steps. The first step involved <br />
methylation of indole to give N-methylindole (4) in 87% yield which on Vilsmeier-Haack formylation in the next step <br />
gave new ketone (S) in 67% yield. Sodium borohydride reduction of the new carbonyl compound (S) in the last step <br />
afforded the new indole alcohol (3) in 99% yield. Treatment of the secondary alcohol (3) with p-toluene sulfonic <br />
acid has been examined which afford di-(1-methylindol-3 yl)-(p-chlorophenyl)methane (7) in 71% yield. |
