Iodo methane

C. (E)- -Iodo-4 -phenyl-2-butene. In a 20-ml., round-bottomed flask are placed 2.0 g. (0.008 mole) of 2-(4/-phenyl-l -buten-3 -yl)thio-2-thiazoline, 5 ml. of methyl iodide [Methane, iodo-], and 2 ml. of di-methylformamidc. The resulting solution is heated at 75-80° for 2.5 hours under a nitrogen atmosphere (Note 13), cooled, and poured into 10 ml. of water. Extraction with three 12-ml. portions of ether separates the product from water-soluble by-products. The extracts are combined, washed with 8 ml. of 1% aqueous sodium thiosulfate and two 8-ml. portions of water, dried over anhydrous magnesium sulfate, and filtered to remove the drying agent. Removal of ether by distillation at 30° (100 mm.) leaves 1.5-1.7g. (74-82%) of ( )-l-iodo-4-phenyl-2-butene (Notes 14 and 15).
