Steps:
3.c Step c
Step c [4-(Fluoro)benzenesulfonyl]isocyanate Combine N-[(1-oxo-2-oxo-2-chloro)ethyl]-4-(fluoro)benzenesulfonamide (1.70g, 6.4mmol) and o-dichlorobenzene (25mL). Reflux for 16 hours then remove the solvent by fractional distillation (6mm Hg vacuum through a column packed with glass helices). Purify by distillation to give the title compound (1.15g, 32%); bp 80° C.?0.075mm.
