Following the general procedure of Example 41, making non-critical variations but starting with 3-benzoyl-8,9-dichloro-1,2,3,4,5,6-hexahydroazepino[4,5-b]indole, using ethyl crotonate in step 7, and using methanesulfonic acid for the salt formation, the title compound was obtained (mp 225-230° C. [dec.]). 1H NMR (d-DMSO) δ 8.94, 8.12, 4.97, 3.48-3.20, 3.13, 2.77, 2.30, 1.20; IR (drift) 3029, 2979, 2849, 2792, 1683, 1481, 1410, 1312, 1214, 1196, 1184, 1161, 1145,1040, 775 cm−1.
