PROCEDURE FOR THE PREPARATION OF 1,4-BENZODIAZEPINE COMPOUNDS. COMPOUNDS (II) OR (III) ARE REACTED WHERE AND IS LOWER HALOGEN, ALKANOSULPHONYLOXYL OR BENZENOSULPHONYLXYL SUBSTITUTED IN THE LOWER AALALINE ALCOHYL OR A HALOGEN HYDROXIDE, <2. THE COMPOUND (I) IS OBTAINED WHERE X IS OXYGEN, SULFUR, OR AN IMINO GROUP = N-R <4. R <1 IS HYDROGEN, LOWER ALCOHYL, HALOGEN, LOWER ALCOXYL OR NITRO; R <2 IS HYDROGEN, LOWER ALCOHYL, HALOGEN, LOWER ALCOXYL OR NITRO. R <1 AND R <2 ARE LINKED TO NEIGHBORING CARBON ATOMS AND TOGETHER MEAN METHYLENDIOXYL OR ETHYLENDIOXYL. R <3 IS SOME OF THE GROUPS (IV). |
