Procedure

To a solution of 8-(4-(4-methoxyphenyl)-5-(p-tolyl)thiazol-2-yl)-1,4-dioxaspiro[4.5]decane (Reference Example 95) (734 mg, 1.74 mmol) in tetrahydrofuran (8.7 mL), 1.63 M n-butyllithium/solution in n-hexane (1.17 mL) was added at −78° C., and the obtained solution was stirred at the same temperature for 1 hour. The reaction solution was added at −78° C. to a solution of 3-phenyl-2-(phenylsulfonyl)-1,2-oxaziridine (546 mg, 2.09 mmol) in tetrahydrofuran (8.7 mL), and the obtained solution was allowed to warm gradually to room temperature with stirring. Distilled water was added to the reaction solution, and the resulting solution was extracted with ethyl acetate. The organic layer was washed with brine, dried over sodium sulfate and concentrated under reduced pressure. The residue was purified by flash chromatography (silica gel, n-hexane/ethyl acetate) to obtain the captioned compound (417 mg, 0.954 mmol, 55%) as a colorless amorphous product.
