Reaction Steps

To a solution of methylmagnesium bromide (170 mL of a 3.0 M solution in Et2O, 0.51 mmol) in THF at 0° C. was added a solution of 1-[4-({2-piperidin-1-yl-7-[3-(trifluoromethyl)pyridin-2-yl]-6,7,8,9-tetrahydro-5H-pyrimido[4,5-d]azepin-4-yl}amino)phenyl]ethanone (Example 156; 59.8 mg, 0.117 mmol) in THF. The solution was allowed to warm to rt over 1 h, and stirred at rt for an additional 5 min. The reaction mixture was then quenched with satd. aq. NH4Cl and extracted with EtOAc. The organic layers were combined, dried, and concentrated. The crude residue was purified (FCC) to give the title compound (51 mg, 83%).
