Reaction Conditions:

with potassium carbonate in acetone; for 24 h;Reflux;

Steps:

1.20.2.2.10 1-Benzyl-2-methyl-1H-indole-3-carbaldehyde (II-g)

A mixture of 2-methylindole-3- carbaldehyde (10.0 g, 0.063 mol), anhydrous potassium carbonate (52.0 g)t benzyl bromide (11,83 g, 0.069 mol), and acetone (250 ml) was stirred and heated under reflux for 24 h. Filtration and evaporation gave a solid which was recrystallised from ethanol to give the title compound . Yield: 69%;m.p. 135 °C. 1H NMR (300 MHz, DMSO) δ = 10.25 (1H, s), 8.40(1 H, m), 6.83-7.5 (8 H, m), 5.33 (2 H, s), 2.63 (3 H, s).
