Process for 3-hydroxy benzodiazepinones |
| 摘要 |
Conversion of 3-acyloxy-benzodiazepin-2-ones into corresponding 3-hydroxy benzodiazepin-2-ones is carried out efficiently with potassium hydroxide or potassium alkoxide as catalyst in lower alkanol solvent at a pH of 11-11.5. The final products, which include temazepam, are useful as sleep inducers.
