Benzene → N-(2,6-dimethyl-4-chlorophenyl)valine

Participants

Reaction Steps

A mixture of 0.5 g of the m-phenoxybenzyl ester of N-(2,6-dimethylphenyl)valine, 0.21 g of N-chlorosuccinimide and 3 ml of benzene is heated at reflux for 2 hours. The reaction is diluted with hexane, washed with water (2×) and solvent stripped to give the crude product. To the crude product is added 0.1 g of N-chlorosuccinimide and 3 ml benzene. The mixture is heated at reflux for 30 min and then allowed to stand overnight at RT. The reaction is worked up by diluting with hexane, washing with water and stripping off solvent to yield the m-phenoxybenzyl ester of N-(2,6-dimethyl-4-chlorophenyl)valine, MS m/e 437.1 (M+, 15.3).
