Procedure
In the same manner as in Example 80 and using [1]benzothieno[2,3-b][1,5]benzothiazepin-12(11H)-one (500 mg), phosphorus oxychloride (6.3 g), N,N-dimethylaniline (109 mg) and 1-methylpiperazine (5 ml), 12-(4-methylpiperazin-1-yl)-[1]benzothieno[2,3-b][1,5]benzothiazepine (278 mg) was obtained.
