반응 단계
A 1M solution of lithium aluminium hydride in tetrahydrofuran (32.8 ml) was added dropwise to a stirred solution of (RS)-ethyl-(4-benzylpiperazin-2-yl)acetate (D3) (4.3 g, 16.41 mmol) in anhydrous tetrahydrofuran (100 ml) under argon, maintaining the temperature below 10° C. The resultant was stirred for a further 0.25 h, warmed to room temperature and stirred for 2.5 h. Water (8.2 ml), 2N sodium hydroxide (10.2 ml), and water (8.2 ml) were added dropwise sequentially with ice cooling. After 0.2 h sodium sulfate was added, the mixture stirred for 0.2 h then filtered through a short pad of celite. The filtrate was evaporated in vacuo to give the title compound as a pale orange oil (3.3 g, 91%). Mass spectrum (AP+): Found 221 (MH+). C13H20N2O requires 220.
