Procedure
The procedure for thiazole synthesis, described in the preparation of cis-N2-(4-{4-amino-1-[4-(4-methylpiperazino)cyclohexyl]-1H-pyrazolo[3,4-d]pyrimidin-3-yl}phenyl)-4-ethyl-1,3-thiazol-2-amine, was employed with the exception that 3-bromo-2-butanone (0.183 g, 1.21 mmol) was used as the alkylating agent, and the alkylation reaction was conducted at 40° C. for 24 h. Purification of the product by preparative HPLC (25 to 100% acetonitrile in 0.1 M aqueous ammonium acetate over 20 min at 21 mL/min using an 8μ Hypersil HS C18, 250×21 mm column, Rt 6.7-7.7 min) afforded cis-N2-(4-{4-amino-1-[4-(4-methylpiperazino)cyclohexyl]-1H-pyrazolo[3,4-d]pyrimidin-3-yl}phenyl)-4,5-dimethyl-1,3-thiazol-2-amine as an off-white powder (0.069 g, 0.133 mmol); RP-HPLC (25 to 100% acetonitrile in 0.1 M aqueous ammonium acetate over 10 min at 1 mL/min using a 5μ Hypersil HS C18, 250×4.6 mm column) Rt 6.83 min; MS (MH)+ 518.
