Participants

Reaction Steps

N,N-dimethyl-2-(4-aminobutyl)benzofuran-6-carboxamide (13.0 g., 0.05 mole) in tetrahydrofuran (60 ml.) is added dropwise with stirring to lithium aluminum hydride (3.0 g., 0.08 mole) in tetrahydrofuran (60 ml.) at 25°-30° C. The mixture is stirred for 2 hours at 25°-30° C. and then is treated successively with 3 g. of water, 3 g. of 15% sodium hydroxide solution and 9 g. of water. The solid precipitate is removed by filtration. The tetrahydrofuran solution is evaporated at reduced pressure to provide 2-(4-aminobutyl)-6-dimethylaminomethyl)benzofuran.
