3,4-Dimethoxybenzene sulfonyl chloride (11.8 g) in tetrahydrofuran (100 mL) is added slowly with stirring to a mixture of N-methylpropargylamine (3.5 g), triethylamine (5.05 g), and tetrahydrofuran (100 mL). The resulting mixture is refluxed 1 hour, cooled, filtered, and evaporated to dryness. The residue is treated with water, filtered, washed with water, and dried. Recrystallization from ethanol gave 8.7 g of the title product.
