To a solution of (4-(5-fluoro-2-methoxypyridin-4-yl)-3-(1-vinylcyclopentyl)phenyl)methanol (47.0 mg, 144 μmol) in DMF (0.01 mL) and DCM (4.0 mL) was slowly added thionyl chloride (14.7 μL, 201 μmol) at 0° C. After addition, the resulting mixture was stirred at room temperature for 1 hour. The solvent was removed, and the product thus obtained was used in the next step without further purification. 1H NMR (400 MHz, CDCl3) δ ppm 8.01-8.11 (1H, m), 7.98 (1H, m), 7.47 (1H, s), 6.94 (1H, d, J=7.8 Hz), 6.69-6.82 (1H, m), 5.80 (1H, dd, J=17.2, 10.6 Hz), 4.89 (1H, d, J=10.2 Hz), 4.52-4.69 (3H, m), 3.89 (3H, s), 1.68-1.84 (4H, m), 1.49-1.67 (4H, m).
