Methyl 2-(2,3-dihydro-1H-indol-3-yl)acetate → 2-(2,3-Dihydro-1H-indol-3-yl)ethan-1-ol

Participants

Reaction Steps

Methyl (RS)-(2,3-Dihydro-1H-indol-3-yl)acetate (30.0 g, 0.16 mol) was dissolved in tetrahydrofuran (500 mL) and subsequently added to a suspension of lithium aluminium hydride (10.6 g, 0.28 mol) in tetrahydrofuran (500 mL) over a period of 75 min at 33-39° C. The reaction was quenched by sequential addition of water (20 mL), 15% NaOH (10 mL) and water (50 mL), and then MgSO4. The mixture was stirred at room temperature for 1 h, filtered and concentrated in vacuo to give the title compound (24.2 g, 95%).
