To a 20-mL scintillation vial were added the product from Example 104B (54.2 mg, 0.175 mmol), the 2-fluoronicotin-onitrile (Aldrich, 32.1 mg, 0.263 mmol), and anhydrous acetonitrile (2 mL). Neat triethylamine (53.1 mg, 0.525 mmol) was added. The reaction mixture was heated to 60° C. in a heated shaker block and mixed for 24 hours. After cooling to room temperature, the volatiles were removed by rotary evaporator. The product was purified by flash chromatography (silica gel: 20-65% ethyl acetate in hexanes) to give 54.6 mg (76%) of the title compound. 1H NMR (DMSO-d6) δ ppm 0.88 (t, J=7.3 Hz, 3H), 1.21-1.34 (m, 3H), 1.52-1.62 (m, 1H), 1.57 (s, 9H), 2.20-2.27 (m, 2H), 2.59-2.64 (m, 2H), 3.35-3.43 (m, 1H), 3.69-3.78 (m, 2H), 3.88-3.95 (m, 1H), 4.04-4.09 (m, 1H), 6.69 (dd, J=7.5, 4.8 Hz, 1H), 7.93 (dd, J=7.9, 2.0 Hz, 1H), 8.31 (dd, J=4.8, 2.0 Hz, 1H), 8.57 (s, 1H). MS (ESI+) m/z 412 (M+H)+.
