YieldReaction ConditionsOperation in experiment
General procedure: Triphosgene (0.14 g, 0.48 mmol) was dissolved in anhydrous CH2Cl2 (15 mL) and the mixture was stirred on the ice-bath for 15 min. 3-Bromo-5-(trifluoromethyl)aniline (0.3 g, 1.2 mmol) in anhydrous CH2Cl2 (10 mL) was added dropwise to the above mixture and stirring continued for 20 min. Et3N (0.2 mL, 1.44 mmol) diluted with CH2Cl2 (5 mL) was then added into the mixture. Stirring was continued for 20 min and a solution of Et3N (0.2 mL, 1.44 mmol), 4-pyridin-3-ylaniline (5) (0.2 g, 1.2 mmol) in anhydrous CH2Cl2 (20 mL) was added. After completion of the action, the reaction was quenched with dilute Na2CO3. The organic layer was washed with water and brine, and dried over Na2SO4. After filtration and concentration in vacuo, the residues was purified by silica gel flash chromatography (PE/AcOEt = 6:1) yielding (L1). yield 73%

YieldReaction ConditionsOperation in experiment
94% With 2,4,6-tripropyl-1,3,5,2,4,6-trioxatriphosphinane-2,4,6-trioxide; N-ethyl-N,N-diisopropylamine; In dichloromethane; ethyl acetate; at 0 - 20℃; for 1.0h; General procedure: To a stirred solution of 5-amino-1-naphthol (126 mg, 0.792 mmol) and <strong>[70395-35-6]sodium chlorofluoroacetate</strong> (159 mg,1.18 mmol) in dichloromethane (8 mL) was added T3P (50 wt%solution in AcOEt, 701 μL, 1.18 mmol) and N,N-diisopropylethylamine(DIPEA) (273 μL, 1.57 mmol) at 0C. Afterstirred at ambient temperature for 1 h, the reaction mixturewas diluted with water and extracted thrice with CHCl3. Thecombined organic layers were washed with brine, dried overNa2SO4, filtered and concentrated in vacuo. The residue waspurified by flash column chromatography on silica gel (hexane/AcOEt = 3 : 1) to afford the title compound (37.2 mg, 18% yield) as a pale purple solid.
