After 48 hours, cool the mixture to ambient temperature and dilute with ethyl acetate. Wash the organic layer with 0.1N NaOH and brine. Dry (sodium sulfate) and concentrate the organic layer to residue. Purify the residue on silica gel using dichloromethane/methanol (90:10) to give 257.1 mg (48%) of a yellow foam: mp=64° C. dec; mass spectrum (ion spray): m/z =433.1 (M+1).
