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.
