Procedure

N-{[1,6-Diethyl-4-(tetrahydro-2H-pyran-4-ylamino)-1H-pyrazolo[3,4-b]pyridin-5-yl]methyl}-4-({8-[(2-hydroxyethyl)(methyl)amino]octanoyl}amino)benzamide [the “free base”, 100 mg, about 0.161 mmol, as a substantially amorphous form thereof, as prepared in Example 1B (alternative preparation no. 2)] and (+)-camphorsulfonic acid (37.4 mg±1 mg, 1 equivalent) were suspended in ethyl acetate (6 ml). The resulting suspension was left to temperature cycle between 0° C. and 40° C. overnight. The next day, a suspension had formed, from which the resulting solid was isolated by filtration, washed with ethyl acetate (1 ml) and dried at 40° C. under vacuum overnight. 82.2 mg of dried solid was obtained. NMR data appears to support a stoichiometry consistent with the solid product being substantially a mono-(+)-camphorsulfonate.
