| titleOfInvention | Process for producing 10H-dibenzo [b, f] [1,4] thiazepin-11-one |
| abstract | 2- (2-nitro-phenylsulfuryl) benzoic acid is prepared by reacting dithiosalicylic acid with 1-chloro-2-nitrobenzene in a basic aqueous solution in the presence or absence of a reducing agent; 2- (2- Nitrophenylsulfuryl) benzoic acid is subjected to nitro group reduction in the presence of hydrogen, solvent and heterogeneous metal catalyst to produce 2- (2-aminophenylsulfuryl) benzoic acid; presence of acid catalyst in organic solvent Alternatively, a method for producing 10H-dibenzo [b, f] [1,4] thiazepin-11-one is disclosed which comprises directly cyclizing 2- (2-aminophenylsulfuryl) benzoic acid in the absence. The method according to the present invention is economical because it uses inexpensive raw materials, and is environmentally friendly and efficient by minimizing the use of organic solvents and performing direct cyclization without carboxylic acid activation.
