Yield	Reaction Conditions	Operation in experiment
	With phosphorus tribromide; In dichloromethane; at 20.0℃;	To a solution of (5-fluoropyridin-3-yl)methanol (430 mg, 3.4 mmol) in anhydrous dichloromethane (30 mL) was added dropwise phosphorus tribromide (650 muL, 6.8 mmol). The mixture was stirred at room temperature overnight. Dichloromethane was evaporated. The residue was dried in vacuo, affording 3-(bromomethyl)-5- fluoropyridine hydrobromide. The product was used without further purification.

	With triethylamine; In ethanol; at 20.0℃;	A mixture of <strong>[1256561-65-5]3-(bromomethyl)-5-fluoropyridine hydrobromide</strong> (3.4 mmol), 6-methyl- 2-sulfanylpyrimidin-4-ol (370 mg, 2.6 mmol), and triethylamine (1.7 mL, 12.0 mmol) in absolute ethanol (40 mL) was stirred at room temperature overnight. The solid material was removed by filtration. The filtrate was recovered, evaporated, co- evaporated with EtOAc (20 mL), and then dried in vacuo. The solid residue was treated with water (100 mL). The solid product was recovered by filtration, washed with water (1 x 20 mL) and diethyl ether (2 x 20 mL), and then dried in vacuo, affording the 2-[(5-fluoropyridin-3-yl)methyl]sulfanyl}-6-methylpyrimidin-4-ol (200 mg, 23% yield); 1H NMR (400 MHz, OMS0-d6): delta 2.21 (s, 3H), 4.41 (s, 2H), 6.02 (s (br), IH), 7. 80 (m, IH), 8.05 (dd, IH, / = 2.0 Hz, 7.6 Hz), 8.46 (d, IH, J = 2.7 Hz), 8.54 (t, IH, J = 1.6 Hz); M+ 252.

Yield	Reaction Conditions	Operation in experiment
	With potassium carbonate; In N,N-dimethyl-formamide; at 20.0℃;	Potassium carbonate (193 mg, 1.396 mmol) and <strong>[1256561-65-5]3-(bromomethyl)-5-fluoropyridine hydrobromide</strong> (151 mg, 0.558 mmol; Sunshine Chemlab) were added to a solution of 2.2.7-trifluoro-8-(1-hydroxyethyl)-2H-1 ,4-benzoxazin-3(4H)-one (138 mg; may be prepared as described in intermediate 1 1 ) in dry DMF (5 ml_). The mixture was stirred at room temperature overnight. The solvent was evaporated and the residue was dissolved in DCM (3 ml.) and 10% w/v aqueous citric acid (2 ml_). The layers were separated and the aqueous was extracted with DCM (2 x 2 ml_). The combined organic layers were dried (hydrophobic frit) and evaporated to give a brown oil (137 mg). This was purified by MDAP (formic acid method) to give a brown oil (104 mg). 96 mg of this racemic mixture was resolved using a Chiralpak AS column eluting with heptane: ethanol (90:10) v/v pump-mixed. Using these conditions the faster-running enantiomer 2,2,7-trifluoro-4-[(5- fluoro-3-pyridinyl)methyl]-8-[(1 S)- 1 -hydroxyethyl]-2H-1 ,4-benzoxazin-3(4H)-one (42 mg, Compound 99) and the slower-running enantiomer 2,2,7-trifluoro-4-[(5-fluoro-3- pyridinyl)methyl]-8-[(1 R)-1-hydroxyethyl]-2H-1 ,4-benzoxazin-3(4H)-one (40 mg, Compound 100) were obtained in >99% enantiomeric excess. 1H NMR (CD3OD) delta: 1.60 (3H, d), 5.32 - 5.40 (1 H, m), 7.01 (1 H, t), 7.18 - 7.25 (1 H, m), 7.57 (1 H, d), 8.38 - 8.45 (2H, m). m/z [M+H]+: 356.9 Retention time 0.85 min (LC/MS method 3). The absolute configurations were determined by ab initio vibrational circular dichroism.

Yield	Reaction Conditions	Operation in experiment
37%		A solution of 3 -(bromomethyl)-5 -fluoro-pyridine hydrobromide AA (53 mg, 0.19 mmol, 2.1 eq.) and sodium hydride (6.6 mg, 0.28 mmol, 3.0 eq.) in DMF (500 1iL) were stirred for 10 minutes. Compound Z (prepared according to methods described in Example 5) (25 mg, 0.092 mmol, 1.0 eq.) was added. After 18 hours, the reaction was diluted with ethyl acetate and washed with water and brine twice. The organic layerss were combined, dried over magnesium sulfate, filtered, and concentrated in vacuo. Purification by reverse phase HPLC afforded 12.8 mg (3 7%) of the title compound. ?H NMR (400 MHz, DMSO-d6) (5 8.47 (d, J= 2.8 Hz, 1H), 8.43 (s, 1H), 8.25 (s, 1H), 7.66 (s, 1H), 7.57- 7.53 (m, 2H), 7.36 (dd, J 1.92, 9.72 Hz, 1H), 7.29-7.25 (m, 2H), 4.41 (s, 2H), 3.49 (t, J= 5.2 Hz, 2H), 3.18 (t, J= 5.2 Hz, 2H), 2.76 (s, 3H); ES-MS [M+1]: 381.2.
