To a 4-mL vial containing 4-(1-(3-amino-4-methylbenzoyl)azepan-4-yl)benzonitrile (compound 40.5, 44 mg, 0.13 mmol, 1.0 equiv) was added dichloromethane (1 mL) and N,N-diisopropylethylamine (35 μL, 0.20 mmol, 1.5 equiv). A solution of 6-fluoronicotinoyl chloride (22 mg, 0.14 mmol, 1.05 equiv) in dichloromethane (1 mL) was added dropwise over about 2 minutes. The resulting mixture was stirred at room temperature for 19 hours then diluted with dichloromethane (5 mL) and washed with 1 M NaH2PO4 (3 mL), saturated sodium bicarbonate (3 mL) and brine (3 mL). The organics were dried (Na2SO4), filtered and concentrated to obtain the title compound as a brown wax (64 mg, theoretical). m/z (ES+) 457 (M+H)+.
