Reaction Steps

A solution of 2-chloro-5-fluoropyrimidine (10 mmol) in ethanol (15 ml) was added dropwise over 5 min to a solution prepared from thiophenol (10 mmol) and 0.43 M NaOEt in ethanol (25 ml). Subsequently the mixture was heated to boiling and refluxed for 2 hours, filtered hot, the filtrate evaporated, the residue extracted with chloroform (50 ml), the chloroform solution shaken with 2 M NaOH (2×10 ml), then shaken with water (10 ml) and the solution evaporated; yield 69%. 1H NHR (CDCl3): δ7.4 (Pyr), 8.23 (H-4, H-6).
