Abstract
C 10H7FN2O4S, monoclinic, P121/c1(no.14), a =7.8292(8)Å, b =12.316(1)Å, c =13.422(1) Å, b =123.497(4)°,V =1079.3Å 3 , Z =4,R gt (F) =0.051, wR ref (F 2 ) =0.118, T =273 K. Source of materialPhenylsulfonyl-5-fluorouracil was prepared by reacting 5fluorouracil (0.01 mol) with triethylamine (0.02 mol) and phenylsulfonyl chloride (0.02 mol) in anhydrous dichloromethane over 12 hours (353 K, reflux), followed by aqueous work-up and extraction.The purified product was dissolved in 95 % ethanol and single crystals were separated after 10 days.
