실험 절차
A mixture of (R)-7-(5-bromo-2-fluoro-phenyl)-7-methyl-5,5-dioxo-5λ6-thia-8-aza-spiro[3.5]nonan-9-thione (1.05 g, 2.68 mmol, Eq: 1.00) and ammonia (7 N in MeOH) (19.1 ml, 134 mmol, Eq: 50) was stirred in a sealed tube for 40 hours at 60° C. Extracted with ethyl acetate and sat. NaHCO3-sol., dried the organic layer over Na2SO4, filtered and evaporated. The residue was chromatographed on 20 g silica gel with ethyl acetate to give (R)-7-(5-bromo-2-fluoro-phenyl)-7-methyl-5,5-dioxo-5λ6-thia-8-aza-spiro[3.5]non-8-en-9-ylamine (560 mg, 1.49 mmol, 55.8% yield) as a white solid. MS (ISP): m/z=375.0 [M+H]+ and 377.4 [M+2+H]+.
