反応手順

Initially, 3.1 g of 3-dimethylaminobenzylchloride hydrochloride was added to a mixture of 0.8 g of 5,5-dimethyl-2,4-dithiohydantoin and 1.34 g of sodium methoxide in 50 mL of methanol (MeOH). The reaction mixture was treated following the procedure used in Example 56, and purified by column chromatograph (CHCl3) to give the desired compound in the form of a syrup. The yield of this compound was 1.65 g with a yield ratio of 82.9%.
