実験手順
To a solution of 4-(4-(7-(4-Cyano-3-(trifluoromethyl)phenyl)-8-oxo-6-thioxo-5,7 -diazaspiro[3.4]octan-5-yl)phenyl)butanoic acid, RD141 (Formula 51) (60 mg, 0.12 mmol) in DMF (3 mL) was added thionyl chloride (0.01 mL, 0.15 mmol) at 0° C. The mixture was stirred at 0° C. for 1 hour. Then ammonia was bubbled into the mixture. The mixture was partitioned with ethyl acetate (25 mL) and water (25 mL). The organic layer was dried over MgSO4, concentrated and chromatographed (dichloromethane:acetone, 70:30) to yield 4-(4-(7-(4-Cyano-3 -(fluoromethyl)phenyl)-8-oxo-6-thioxo-5,7-diazaspiro[3.4]octan-5-yl)phenyl)butanamide, RD130 (Formula 52) (37 mg, 61%) as a white powder. 1H NMR δ 7.97 (d, 1H, J=1.8 Hz), 7.95 (d, 1H, J=8.3 Hz), 7.85 (dd, 1H, J=8.3 Hz), 7.39 (d, 2H, J=8.3 Hz), 7.22 (d, 2H, J=8.3 Hz), 5.59 (br s, 2H), 2.77 (t, 2H, J=7.5 Hz), 2.62-2.68 (m, 2H), 2.51-2.59 (m, 2H), 2.31 (t, 2H, J=7.5 Hz), 2.16-2.25 (m, 1H), 2.05 (p, 2H, J=7.5 Hz), 1.57-1.70 (m, 1H).
