Procedure

To a solution of Intermediate 1 (505 mg, 1.31 mmol) in N,N-dimethylformamide (3 mL) was added 2-chloromethyl-3,5-difluoro-pyridine from Step C (214 mg, 1.31 mmol), potassium carbonate (452 mg, 3.27 mmol) and 18-crown-6 (40 mg). The slurry was heated at 60° C. for eighteen hours. After cooling the reaction was partitioned between ethyl acetate and water. The organic layer was washed with water and brine and dried over magnesium sulfate. The slurry was filtered and concentrated in vacuo. The crude material was purified using normal phase chromatography (ethyl acetate/heptane) to provide the title compound as a colorless oil (250 mg, 37% yield). MS (M+H): 514; 1H NMR (400 MHz, chloroform-d) δ ppm, 1.64 (s, 6H), 2.16 (s, 3H), 2.21 (s, 3H), 5.62-5.72 (m, 2H), 7.28-7.30 (m, 1H), 7.54-7.58 (m, 2H), 7.92 (s, 1H), 8.14 (d, J=8.21 Hz, 1H), 8.40 (s, 1H), 8.78 (d, J=5.47, 1H).
