N,1-dimethylindole-2-carboxamide → methyl((1-methyl-1H-indol-2-yl)methyl)amine

Participants

Reaction Steps

A 3-liter 3-necked roundbottom flask equipped with overhead stirring was charged with N,1-dimethylindole-2-carboxamide (23.4 g, 124.6 mmole) and anhydrous THF (170 mL). The solution was stirred while a solution of LiAlH4 in THF (1.0 M, 250 mL, 250 mmole) was added via syringe. Gas was evolved during the addition of the first 50 mL of LiAlH4 solution. When the addition was complete, the resulting light yellow solution was heated at gentle reflux. After 24 hr, the reaction was cooled in ice and quenched by the sequential dropwise addition of H2O (9.5 mL), 15% NaOH (9.5 mL), and H2O (28.5 mL).
