[(2R)-1-(2-aminoethyl)pyrrolidin-2-yl]methanol

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To tetrahydrofuran (30 ml) was added lithium aluminum hydride (720 mg, 19.0 mmol) and the mixture was stirred under ice-cooling. Then, a solution (20 ml) of the compound (1.00 g, 6.32 mmol) obtained in step A in tetrahydrofuran was gradually added, and the mixture was heated under reflux for 2 hr. The reaction mixture was cooled, water (0.72 ml), 1N aqueous sodium hydroxide solution (1.44 ml) and water (0.72 ml) were slowly added in this order with stirring, and the mixture was stirred at room temperature for 1 hr. The insoluble material was filtered off through celite, and the solution was concentrated under reduced pressure to give the title compound (718 mg, yield 79%) as a yellow oil. cooling the mixture was heated under reflux for 2 hr The reaction mixture was cooled with stirring the mixture was stirred at room temperature for 1 hr The insoluble material was filtered off through celite the solution was concentrated under reduced pressure
