Reaction Steps

A mixture of 4-[(4-methyl-1-piperazinyl)methyl]-N-[4-methyl-3-[[4-(3-pyridinyl)-2-pyrimidinyl]amino]phenyl]-benzamide (4.94 g, 10 mmol) and 4,4′-methylenebis[3-hydroxy-2-naphthoic acid (Fluka, Buchs, Switzerland; 3.88 g, 10 mmol) in ethanol (50 mL) is heated. Water (25 mL) is then added. Upon cooling, the product crystallises and is filtered-off and dried to afford 4-[(4-methyl-1-piperazinyl)methyl]-N-4-methyl-3-[[4-(3-pyridinyl)-2-pyrimidinyl]amino]phenyl]-benzamide, pamoate as a pale-yellow solid, having the following analytical properties: Analysis found: C, 69.12; H, 5.62; N, 10.88%; H2O, 2.50%. Calculated for C52H47N7O7-1.26 H2O: C, 69.04; H, 5.52; N, 10.84%; H2O, 2.51%.
