Procedure
4-Phenoxybutylsulfonyl fluoride (17) was synthesized as in 13.1 using 16 (0.4 g, 1.6 mmol) and NH4F (0.118 g, 3.2 mmol) in dry acetone (20 mL). Purification by flash column chromatography on silica gel gave 17 (0.338 g, 91% yield) as a white solid (m p 74-76° C.) 1H NMR (500 MHz, CDCl3) δ 7.29 (t, J=7.5 Hz, 2H), 6.97 (t, J=7.5 Hz, 1H), 6.89 (d, J=7.5 Hz, 2H), 4.03 (t, J=5.5 Hz, 2H), 3.52-3.48 (m, 2H), 2.20 (quintet, J=7.7 Hz, 2H), 2.00 (quintet, J=8.0 Hz, 2H).
