Versuchsvorschrift

4.8 g (10 mmol) of N-[4-methyl-3-(4-pyridin-3-yl-pyrimidin-2-ylamino)-phenyl]-4-piperazin-1-ylmethyl-benzamide are dissolved in 20 ml of ethanol under heating and 0.99 g of methanesulfonic acid are added. After addition of ethyl acetate the product cristallizes. Drying at 50 mbar and 60° C. yields N-[4-methyl-3-(4-pyridin-3-yl-pyrimidin-2-ylamino)-phenyl]-4-piperazin-1-ylmethyl-benzamide methanesulfonate; Rf=0.17 (methylene chloride:ethyl acetate:methanol:conc. aqueous ammonium hydroxide solution=60:10:30:2); tR (HPLC)2) 14.6 min; m.p. 242-245° C.
