Ammonia → 1-Amino-3-(morpholin-4-yl)propan-2-ol

Participants

Reaction Steps

4-Oxiranylmethyl-morpholine 53b (6.3 g, 44 mmol) was added slowly with ammonia (450 ml, 25%, 6.6 mol) while maintaining the temperature below 0° C. in an ice-water bath. Upon completion of the addition, the reaction mixture was allowed to warm up to room temperature and stirred for 18 hours. After thin lay chromatography showed the disappearance of starting materials, the reaction mixture was concentrated under reduced pressure to obtain the title compound 1-amino-3-morpholin-4-yl-propan-2-ol 53c (7 g, yield 99%) as a white solid.
