Methanesulfonic Acid → (2-Chloro-3-trifluoromethyl-benzyl)-(2,2-diphenyl-ethyl)-{3-[6-(4-methyl-piperazin-1-yl)-pyridin-2-yloxy]-propyl}-amine dimesylate salt

Participants

Reaction Steps

Following the procedure of Example 6(d), except 6-(4-methyl-piperazin-1-yl)-pyridin-2-ol and N-(2,2-Diphenylethyl)-N-(3-hydroxy-propyl)-N-(2-chloro-3-trifluoromethyl-benzyl)amine were used instead of 5-(3-hydroxy-benzyl)-ethoxymethyl-1,2,3,4-tetrazole and 3-bromo-propanol in step 6(d), the title compound was synthesized as the free base. The tertiaryamine was then dissolved in dichloromethane and two equivalents of methanesulfonic acid were added to afford the title compound as the dimesylate salt, 47 mg (19% yield), as a white solid. MS (ESI) 623.4 (M+).
