Reaction Steps

To a solution of N-[1-(3-bromo-5-chloro-4-fluoro-2-methoxyphenyl)ethyl]-9-(tetrahydro-2H-pyran-2-yl)-9H-purin-6-amine (50 mg, 0.10 mmol, from Example 187, Step 7) in water (0.21 mL) was added 1,2-dimethoxyethane (0.7 mL), potassium carbonate (14 mg, 0.10 mmol), pyridine:trivinylboroxin (1:1) (26 mg, 0.10 mmol) and tetrakis(triphenylphosphine)Pd(0) (5.2 mg, 0.0045 mmol). The mixture was bubbled with nitrogen for five min and heated at 80° C. overnight. The reaction was diluted with water and EtOAc. The combined organic layers were washed with brine, dried over sodium sulfate and concentrated. Purification on silica gel using 0-100% EtOAc in hexane gave the desired compound (29 mg, 60%). LCMS calculated for C21H24ClFN5O2 (M+H)+: m/z=432.2. found: 432.1.
