Procedure

Cesium carbonate (3000 mg, 10 mmol) was added to a mixture of 3-methyl-1H-pyrazolo[3,4-d]pyrimidin-4-amine (1100 mg, 7.1 mmol) and 5-[3-chloro-5-(1-chloroethyl)-2-cyano-6-methoxyphenyl]-N,N-dimethylpyridine-2-carboxamide (1.8 g, 4.8 mmol) in N,N-dimethylformamide (50 mL). The reaction was stirred at 80° C. for 3 hrs and was allowed to cool to room temperature. The reaction was diluted with EtOAc, washed with water, brine, dried over Na2SO4, filtered and concentrated to give the crude product. This was purified by FCC on silica gel eluting (hexanes/10% EtOH in EtOAc, 0-100%) gradient to give the title compound as light yellow oil (2.0 g, 80%). LCMS calculated for C24H24ClN8O2 (M+H)+: m/z=491.1; found: 491.2.
