  • Process for producing new oxazepine derivatives
    Publication number: 20020133004
    Abstract: A process for producing a 5-substituted-5,11-dihydro-debenzo [b,e] [1,4] oxazepine compound, wherein a [2-(2-bromobenzyloxy)phenyl]amide derivative having a substituent introduced through amido bond, the substituent locating at the 5-position of the final compound, as the starting material, is subjected to the intramolecular arylation and then the obtained product is reduced. In particular, (R)-1-[(4-methoxyphenyl)acetyl]pyrrolidine-2-carboxylic acid [2-(2-bromo benzyloxy)phenyl]amide is subjected to the intramolecular arylation to obtain (R)-[[2-(5,11-dihydro-dibenzo[b,e][1,4]oxazepine-5-carbonyl)pyrrolidin]-1-yl]-2-(4-methoxyphenyl)ethanone and then this product is reduced.
