Reaction Steps

Lithium aluminium hydride (532 mg) was added in portions to a solution of (R)-6-ethyl-4-methyl-3,4-dihydro-2H-pyrazino[1,2-a]indol-1-one (800 mg, 3.50 mmol) in tetrahydrofuran (30 mL) and the resulting suspension was heated to reflux for 1 h. After cooling the reaction was quenched by careful addition of 1 M aqueous sodium potassium tartrate solution (50 mL). Then methanol (50 mL) and ethyl acetate (50 mL) were added, the organic layer was separated, washed with brine, dried (MgSO4), and evaporated to yield the title compound (750 mg, 100%). White solid. ISP-MS: m/e=215.3 ([M+H]+).
