Procedure
To a slurry of 182 in tetrahydrofuran (10 ml) and triethylamine (0.3 ml) was added 3-bromo-4-chloro-1H-pyrazolo[3,4-d]pyrimidine (63 mg). The mixture was shaken at 50° C. for 24 hours. After cooling to room temperature the mixture was poured into ethyl acetate (150 ml) washed with water (2×200 ml) and the organic layer dried over anhydrous magnesium sulfate. Evaporation to dryness gave a yellow solid which was purified by silica gel chromatography eluting with 60-100% ethyl acetate in hexanes to 1% methanol in ethyl acetate yielding N1-(3-bromo-1H-pyrazolo[3,4-d]pyrimidin-4-yl)-N3-(7-methoxy-3-(2-(methylamino)pyrimidin-4-yl)naphthalen-1-yl)propane-1,3-diamine 183 as a yellow powder (43 mg).
