Reaction Steps

A solution of ethyl 7-hydroxychroman-2-carboxylate (5.0 g, 22.5 mmol) in THF is treated with N-chlorosuccinimide (NCS) (3.6 g, 27 mmol), stirred for 40 hr and concentrated in vacuo. The resultant residue is purified chromatographically (silica gel/20% EtOAc in hexanes as eluent) to give the title product, 3.0 g (52% yield), identified by NMR and mass spectral analyses.
