Dicyclohexylcarbodiimide → Phenoxyacetoxysuccinimide

Participants

Reaction Steps

A suspension of phenoxyacetic acid (15.2 g, 100 mmol) and N-hydroxysuccinimide (11.5 g, 100 mmol) in ethyl acetate (300 ml) was cooled in an ice bath, treated with N,N'-dicyclohexylcarbodiimide (20.6 g, 100 mmol) and stirred for 1 hour at 0° and then overnight at room temperature. The precipitate which formed was filtered; the filtrate was evaporated to dryness; and the residue was crystallized from ethyl acetate to yield 15.0 g of N-(phenoxyacetyloxy)succinimide.
