Aluminium lithium hydride → 5-(2-Diethylamino-ethyl)-2-hydroxymethyl-3-trifluoromethyl-1,5,6,7-tetrahydro-pyrrolo[3,2-c]pyridin-4-one

Participants

Reaction Steps

A stirred solution of lithium aluminum hydride (396 mg, 10.43 mmol) in 6 ml of anhydrous tetrahydrofuran was cooled down to 0° C. in an ice-water bath, added slowly dropwise with 5-(2-diethylamino-ethyl)-3-trifluoromethyl-4-oxo-4,5,6,7-tetrahydro-1H-pyrrolo[3,2-c]pyridine-2-carboxylic acid ethyl ester (1.63 g, 4.35 mmol) in 10 ml of tetrahydrofuran. Upon the completion of the addition, the reaction mixture was stirred at room temperature for 1 hour and filter through a pad of Celite. The filtrate was evaporated under reduced pressure to give the crude product 5-(2-diethylamino-ethyl)-2-hydroxymethyl-3-trifloromethyl-1,5,6,7-tetrahydro-pyrrolo[3,2-c]pyridin-4-one (1.208 g, 83.4%) as a yellow oil which was used as such.
