YieldReaction ConditionsOperation in experiment
100%
Stage #1: With sodium hydride In N,N-dimethyl-formamide at 20℃; for 0.5 h;
Stage #2: at 20℃; for 3.5 h;
Reference Example 12 [0441] Step 1 [0442] To a solution of Compound vii-2 (2.0g, 11.49mmol) in DMF (20mL) was added sodium hydride (0.644g, 16.09mmol) at room temperature, and the mixture was stirred for 30 minutes. Iodoethane (1.858mL, 22.99mmol) was added to the mixture and the resulting mixture was stirred for additional 3.5 hours at room temperature. To the reaction mixture was added water, and the mixture was extracted with ethyl acetate. The organic layer was washed by water and brine, dried over anhydrous magnesium sulphate, and concentrated in vacuo. The resulting residue was purified by silica gel column chromatography (hexane-ethyl acetate) to give Compound vii-3 (2.32g, Yield 100percent). [0443] 1H-NMR (CDCl3) δ: 8.03 (1H, d, J = 2.75 Hz), 7.35 (1H, d, J = 8.69 Hz), 7.07 (1H, dd, J = 8.62, 2.97 Hz), 4.05 (2H, q, J = 6.91 Hz), 1.43 (3H, t, J = 6.94 Hz).

YieldReaction ConditionsOperation in experiment
2.9%
Stage #1: at 150℃; for 8 h;
Stage #2: With potassium hydroxide In water
Step 2; 2-Bromo-5-trifluoromethoxy-pyridine:; Into a 50 mL sealed tube was placed 6-bromopyridin-3-ol (2.5 g, 14.37 mmol), perchloromethane (6.6 g, 42.86 mmol) and antimony pentafloride (101 g, 465.44 mmol). The resulting solution was heated at 1500C for 8 hours. After cooling to room temperature, the reaction mixture was poured into ice water and neutralized with saturated KOH. The resulting solution was extracted with EtOAc (100 ml x 2) and the organic layers combined and dried over MgSO4. The solvent was concentrated to afford O.lg (2.9percent) of 2-bromo-5-(trifluoromethoxy)pyridine.
