Procedure
To a solution of toremifene base (1.094 g, 0.0027 moles) and refluxing diethyl ether (15 ml) was slowly added methanesulfonic acid (190 μl, 0.0029 moles). The refluxing mixture was stirred for a while and cooled to room temperature. The mixture was stirred additional 30 min. After filtration the mesylate of toremifene was obtained (yield 95%) having melting point of 185° C. 1H-NMR (d6-DMSO) d 7.41 (t, 2H), 7.35-7.27 (m, 3H), 7.27-7.12 (m, 5H), 6.81 (d, 2H), 6.69 (d, 2H), 4.18 (t, 2H), 3.43 (t, 4H), 2.85 (t, 2H), 2.82 (s, 6H), 2.32 (s, 3H).
