Benzene → 2-Methylbut-3-yn-2-yl 2-methylprop-2-enoate

Participants

Reaction Steps

A reactor was charged with 550 parts of benzene, 74 parts of pyridine and 65.5 parts of 2-methyl-3-butyn-2-ol. To this were added 90 parts of methacryl chloride dropwise over one hour while keeping the inner temperature at 20° C. Then the reaction mixture was kept at 50° C. for 6 hours, suction filtered, evaporated and distilled in vacuo. 2-Methyl-3-butyn-2-yl methacrylate boiling at 56°-58° C./12 mmHg was obtained in a yield of 62% of theory. The product was identified by the IR spectrum thereof.
