83.2% | To a mixture of compound 5D (4.00 g, 10.14 mmol) and hydroxyethylpiperazine (6.60 g, 50.69 mmol) in n-butanol (40 mL) was added DIPEA (3.53 mL, 20.26 mmol). The slurry was heated at 118°C for 4.5h, then cooled slowly to room temperature. The solid was collected by vacuum filtration, washed with n- butanol (5 mL), and dried. The product (5.11 g) was dissolved in hot 80percent EtOH-H2O (80 mL), and the solution was clarified by filtration. The hot solution was slowly diluted with water (15 mL) and cooled slowly to room temperature. The solid was collected by vacuum filtration, washed with 50percent ethanol-water (5 mL) and dried affording 4.27 g (83.2 percent yield) of N- (2-chloro-6-methylphenyl)-2- (6- (4- (3- hydroxyethyl) piperazin-1-yl)-2-methylpyrimidin-4-ylamino) thiazole-5-carboxamide as monohydrate. 1H NMR (400 MHz, DMSO-d6) # 2.23 (s, 3H), 2.40 (s, 3H), 2.42 (t, 2H, J=6), 2.48 (t, 4H, J=6.3), 3.50 (m, 4H), 3.53 (q, 2H, J=6), 4.45 (t, 1H, J=5.3), 6.04 (s, 1H), 7.25 (t, 1H, J=7.6), 7.27 (dd, 1H, J=7.6, 1.7), 7.40 (dd, 1H, J=7.6, 1.7), 8.21 (s, 1H), 9. 87 (s, 1H), 11.47. | |
Example 23; Procedure for the Preparation of Dasatinib Form H1-7 (Monohydrate)A mixture of compound 1 (133.9 mg, 0.5 mmol), N-(2-hydroxyethyl)piperazine (260.4 mg, 2 mmol) and N-ethyldiisopropylamine (0.174 ml, 1 mmol) in DMF (0.5 ml) was stirred at 100° C. for 2.5 h. H2O (3 ml) was added to the solution at the same temperature. A gummy product precipitated. The suspension was allowed to cool slowly to room temperature and stirred for 2 h at room temperature. The product was filtered washed with H2O (2.x.) and dried on the filter. Yield: 140 mg. |
