Reaction Steps

To a suspension of 2.74 g of 3-iodophthalic anhydride in 8 ml of acetonitrile cooled with ice was slowly added dropwise a solution of 1.19 g of 1-methyl-3-methylthiopropylamine in 3 ml of acetonitrile. After completion of the dropping, a reaction was carried out at room temperature for 3 hours with stirring. After completion of the reaction, the deposited crystal was collected by filtration and washed with a small quantity of acetonitrile. Thus, 3.5 g of the objective compound was obtained.
