Reaction Steps
A mixture of 3,4,4-trifluoro-3-butenoyl chloride (2.5 g, 0.0158 mole) and 2-aminoethanethiol hydrochloride (1.14 g, 0.010 mole) is slowly heated to reflux for 15 min. The mixture is cooled to room temperature and treated with dry ether and filtered. The product is recrystallized from absolute ethanol to give 0.8 g of the title compound as a off-white solid, a 34% yield. m.p. 95°-115° C.
