Procedure
In a similar manner, substituting 10,11-dihydro-11-oxodibenzo[b,f][1,4]thiazepin-7-carboxylic acid for the 10,11-dihydro-11-oxodibenzo[b,f][1,4]thiazepin-3-carboxylic acid in Step A, there is obtained 10,11-dihydro-11-oxodibenzo[b,f][1,4]thiazepin-7-carboxamide. Carboxamides of 10,11-dihydrodibenzo[b,f][1,4]thiazepin-3(or 7)-carboxylic acid or dibenzo[b,f][1,4]thiazepin-3(or 7)-carboxylic acid are prepared by the process of Example 33, by substituting the desired 3(or 7) carboxylic acid for the starting material of Step A.
