실험 절차

The compound of step 1 (0.132 g, 0.634 mmol) was dissolved in THF (0.5 ml) and added to a refluxing suspension of lithium aluminium hydride (122 mg, 3.1 mmol) in THF (1 ml). The mixture was stirred for 1 h under reflux and cooled to room temperature. Diethyl ether (6 ml) was added, followed by EA (0.4 ml). Subsequently, water was added slowly until the alumina salts formed a thick slurry from which the supernatant could be decanted easily. The slurry was repeatedly washed with EA, the combined extracts were dried with sodium sulfate and evaporated to dryness. The residue was purified by RP HPLC (water/ACN gradient) to yield 49 mg of the title compound.
