Benzene → Cyclopropylmethyl dodecanoate

Participants

Reaction Steps

To a stirred solution of 3.01 g. of lauric acid in benzene, under nitrogen, is added 5.8 g. of oxalyl chloride. The mixture is stirred at room temperature for 2 hours and then concentrated in vacuo at 40°. To the concentrate is added fresh benzene and 3.25 g. of cyclopropylmethyl alcohol. The solution is stirred overnight at room temperature and then diluted with water. The reaction mixture is worked up by washing with water and brine, drying over calcium sulfate, concentrating the organic phase under reduced pressure and purifying by distillation to yield cyclopropylmethyl laurate (cyclopropanemethyl-n-dodecanoate), b.p. (bath) 90° at 0.005 mm.
