Reaction Steps

A sample (2.53 g) of triethylamine (25 mmol) was added dropwise to a mixture of 4.01 g 4-vinylbenzyl chloride (25 mmol), 2.00 g monomethyl malonitrile (25 mmol), and 15 mL DMSO at room temperature. The mixture was stirred at room temperature for 17 hours then poured into 100 mL water. A pink solid precipitated and was filtered. The solid was recrystallized from a mixture of methanol and water to give 3.141 g (64%) of pinkish crystals.
