The invention relates to novel methods of preparing a thiazolo[3,4,5-de][4,1]benzothiazepine-type compound and, in particular, methanesulfonate of 6,6-dioxide of 2-imino-9-trifluoromethyl-4,5-dihydro-2H,7H-thiazolo[3,4,5-de][4,1]benzothiazepine and of (R,S) 6-oxide of 2-imino-9-trifluoromethyl-4,5-dihydro-2H,7H-thiazolo[3,4,5-de][4,1]benzothiazepine, as well as the enantiomers and the pharmaceutically-acceptable salts thereof. |
