To a solution of N-[4-[N-methyl-N-(tetrahydropyran-4-yl)aminomethyl]phenyl]-7-(4-morpholinophenyl)-1,1-dioxo-2,3-dihydro-1-benzothiepine-4-carboxamide (36 mg) in ethanol/methanol (10/5 ml) was added at room temperature concentrated hydrochloric acid (0.5 ml), and the mixture was stirred for a few minutes. Insoluble materials were filtered off, and the filtrate was concentrated under reduced pressure. To the residue was added diethylether, and precipitated solid was collected by filtration, which was washed with diethylether to give yellow powder of N-[4-[N-methyl-N-(tetrahydropyran-4-yl)aminomethyl]phenyl]-7-(4-morpholinophenyl)-1,1-dioxo-2,3-dihydro-1-benzothiepine-4-carboxamide dihydrochloride (Compound 2) (34 mg).
