Procedure
A solution of tert-butyl 3-[2,3-dichloro-5-(1-chloroethyl)-6-methoxyphenyl]azetidine-1-carboxylate (1.0 g, 2.5 mmol) and 3-methyl-1H-pyrazolo[3,4-d]pyrimidin-4-amine (0.43 g, 2.9 mmol) in N,N-dimethylformamide (23 mL) was treated with cesium carbonate (1.2 g, 3.8 mmol) and potassium iodide (42 mg, 0.25 mmol) and heated at 100° C. for 10 h. The reaction mixture was diluted with ethyl acetate (75 mL) and water (75 mL). The aqueous layer was separated and reextracted with ethyl acetate (2×50 mL). The combined organic layers were washed with water, saturated sodium bicarbonate solution, and brine, dried over magnesium sulfate, filtered, and concentrated to a crude residue. The crude material was purified by flash column chromatography using methanol in dichloromethane (0%-10%) to give the desired product (0.97 g, 75%). LCMS for C23H29Cl2N6O3 (M+H)+: m/z=507.2, 509.2; Found: 507.0, 509.0.
