실험 절차
6,8-Bis(methanesulfonyloxymethyl)-1,4-dioxaspiro[4.4]nonane (14.90 g, 43.3 mmol) was suspended in aqueous ammonia (35%, 150 ml) and heated for 18 h at 60° C. The reaction was cooled to ambient temperature and concentrated by rotary evaporation. The residue was treated with saturated sodium chloride solution (50 ml) and extracted with chloroform (3×50 ml). The organic extracts were combined, dried over sodium sulfate, filtered and concentrated to yield a brown oil (7.69 g, 100%).
