Reaction Steps

2-Fluorothiophenol (5.0 g, 39 mmol) was dissolved in tetrahydrofuran (50 ml) under a nitrogen atmosphere. Triethylamine (3.94 g, 5.33 ml, 85.8 mmol) was added. Acrylic acid (2.81 g, 2.67 ml, 39 mmol) was dissolved in tetrahydrofuran and added dropwise to the reaction solution over 2 h at room temperature. The mixture was stirred at room temperature overnight. 1M Hydrochloric acid (50 ml) was added and the phases were separated. The aqueous phase was washed with ethyl acetate (2×50 ml). The combined organic phases were dried over magnesium sulphate, filtered and concentrated under vacuum. A yellow oil was obtained which solidified upon storage at room temperature. The solid was triturated with hexane, filtered and dried under vacuum. The title compound was isolated as an off-white solid (4.19 g, 20.9 mmol, 54%).
