Reaction Steps
In a tetrahydrofuran (25 ml) solution of 4,4-dimethyl-5-hexenethioic acid p-tolylamide (1.2 g), a tetrahydrofuran (10 ml) solution of iodine (1.5 g) was added dropwise at 0° C., followed by raising the temperature to room temperature and further stirring overnight. After cooling to 0° C., a tetrahydrofuran (3 ml) solution of DBU (1.8 g) was added dropwise. After raising the temperature to room temperature and further stirring overnight, water was added and the reaction mixture was extracted with ethyl acetate. The organic layer was washed with a saturated saline solution, dried over anhydrous magnesium sulfate, filtered and then concentrated under reduced pressure. The residue was purified by silica gel column chromatography to obtain 0.53 g of the target compound.
