실험 절차

A solution of 2-(Pyridin-3-yloxy)-nicotinic acid (0.250 grams, 1.2 mmole) in thionyl chloride (10 ml) was heated to reflux. After 1 hour the reaction mixture was cooled to room temperature and concentrated under reduced pressure. The resulting residue was suspended in tetrahydrofuran (10 ml) and added dropwise to a solution of (R)-2-hydroxy-1-phenyl ethylamine (0.160 grams, 1.2 mmole) in pyridine (5 ml) at 0° C. After 30 minutes the mixture was warmed to room temperature, stirred at room temperature for 1 hour and concentrated to remove pyridine. The crude product was purified by chromatography on silica gel eluting with ethyl acetate to give a yellow oil. HRMS 336.1324; α=+63.9° 12.3 mg/ml in methylene chloride. 1H NMR (400 mhz, CDCl3) d 2.76 (bs, 1H), 3.95-4.02 (m, 2H), 5.31-5.36 (m, 1H), 7.16-7.40 (m, 1H), 8.19 (dd, J=2.1 Hz, 4.8 Hz, 1H), 8.48-8.61 (m, 4H).
