YieldReaction ConditionsOperation in experiment
With potassium carbonate In N,N-dimethyl-formamide at 20℃; Compound 12: 2,2-difluoro-4-[(5-fluoro-3-pyridinyl)methyl]-8-[(1/?)-2,2,2-trifluoro-1 - hydroxyethyl]-2H-1 ,4-benzoxazin-3(4H)-one and compound 13: 2,2-difluoro-4-[(5- fluoro-3-pyridinyl)methyl]-8-[(1 S)-2,2,2-trifluoro-1-hydroxyethyl]-2H-1,4-benzoxazin- 3(4H) -oneR-stereoisomer S-stereoisomer2.2-Difluoro-8-(2.2,2-trifluoro-1-hydroxyethyl)-2H-1 ,4-benzoxazin-3(4H)-one (105 mg, 0.369 mmol; may be prepared as described in intermediate 5), 3-(bromomethyl)-5- fluoropyridine (100 mg; Sunshine Chemicals) and potassium carbonate (102 mg) were dissolved in DMF (5000 μl) in a 10 ml. round-bottomed flask open to the atmosphere and stirred at RT overnight. The reaction mixture was evaporated to dryness, redissolved in EtOAc (30 ml) and treated with saturated aqueous sodium bicarbonate solution (30 ml). The aqueous layer was extracted with EtOAc (2 x 30 ml) and the organic layers were combined, washed with brine (30 ml), dried over magnesium sulfate, filtered and evaporated to dryness to give the crude product (160 mg) as a colourless oil. The crude product was purified on a 25+S Biotage silica cartridge, eluting with a 0 to 75 % mixture of EtOAc in hexane. This gave the target compound (racemate) (94 mg) as a white solid. 83 mg of this racemic mixture was separated into its constituent enantiomers by chiral preparative HPLC (Chiralpak AD column eluting with heptane: ethanol (70:30) v/v pump- mixed) to give the faster-running enantiomer as a white solid and the slower-running enantiomer as a white solid. These compounds were purified on 12+M Biotage silica cartridges, eluting with 0 to 75 % mixtures of EtOAc in hexane. This gave the faster- running enantiomer as a white solid and the slower-running enantiomer (22 mg, compound 12 or 13) as a white solid. The faster-running enantiomer was purified again by MDAP to give the faster-running enantiomer (12 mg, compound 12 or 13) as a white solid. 1H NMR (CD3OD) δ: 4.52 (2H, q), 4.62 (1 H, q), 6.40 - 6.45 (2H, m), 6.63 (1 H, q), 6.70 (1 H, dt), 7.51 - 7.55 (2H, m). m/z [M+H]+: 393.2. Retention time 0.98 min (LC/MS method 3).

YieldReaction ConditionsOperation in experiment
6% Stage #1: (S)-methyl 2-(3-hydroxypyrrolidin-1-yl)-5-(trifluoromethyl)benzoate With sodium hydride In N,N-dimethyl-formamide; mineral oil at 0℃; for 1h; Stage #2: 3-(bromomethyl)-5-fluoropyridine In N,N-dimethyl-formamide; mineral oil at 0 - 50℃; for 22h; 15 (S)-Methyl 2-(3-hydroxypyrrolidin-1-yl)-5-(trifluoromethyl)benzoate (11b) General procedure: To a solution of 11b (1.50 g, 5.18 mmol) in DMF (20 mL) was added NaH (60% in mineral oil w/w, 0.23 g, 5.75 mmol) in small portions at 0 °C. The reaction mixture was stirred at 0 °C for 1 h, 2-cyclopropylethyl 4-methylbenzenesulfonate, (1.60 g, 6.65 mmol) was added; stirring was continued for 18 h and then heated at 50 °C for 4 h. The reaction mixture was quenched by addition of aqueous saturated NH4Cl solution (10 mL) at 0 °C and extracted with ethyl acetate (100 mL x 3), washed with water and brine' dried over anhydrous Na2SO4 and filtered. The filtrate was concentrated in vacuo, the residue was subjected to column chromatography with a gradient of 10-30% EtOAc in hexanes to give 11c as a colorless oil (1.76 g, 95%). 1H NMR (300 MHz, CDCl3) δ 7.83-7.79 (m, 1H), 7.50-7.45 (m, 1H), 6.80-6.75 (m, 1H), 4.14-4.08 (m, 1H), 3.88 (s, 3H), 3.58-3.38 (m, 4H), 3.36-3.28 (m, 1H), 3.08-3.00 (m, 1H), 2.16-2.00 (m, 2H), 1.43-1.35 (m, 2H), 0.69-0.59 (m, 1H), 0.41-0.35 (m, 2H), 0.19-0.03 (m, 2H); MS (ES+) m/z 358.1 (M+1).
