Versuchsvorschrift
To a stirred suspension of LAH (1.45 g, 38.1 mmol) in dry THF (120 mL) was added a solution of 3-oxo-3-(thiophen-3-yl)propanenitrile (4.8 g, 31.8 mmol) in dry THF (40 mL) dropwise at 0° C. under nitrogen atmosphere. The mixture was warmed to 25° C. and then heated at 65° C. for 6 hours. After cooling to 0° C., a saturated solution of sodium hydroxide (2 mL) was added dropwise and the mixture was filtered. The filtrate was concentrated to dryness to give crude 3-amino-1-thiophen-3-yl-propan-1-ol which was used in next step without further purification.
