실험 절차

A suspension of (S)-1-(2,2,2-trifluoro-ethanoyl)-pyrrolidine-2-carboxylic acid [4-methoxy-3-(3-pyrazin-2-yl-ureido)-phenyl]-amide (Compound 36, Example 6) (22 mg, 0.05 mmol) in a mixture of methanol (MeOH, 5 mL) and water (about 0.25 mL) was treated with KOH (100 mg, large excess). Within 10 minutes, all ingredients were in solution. The reaction mixture was treated with water (20 mL) and extracted with ethyl acetate (2×20 mL). The organic layers were combined and washed with water (10 mL) and brine (10 mL), dried with sodium sulfate, and concentrated to a tan solid (13 mg, 75%). 1H NMR (300 MHz, d6-DMSO) δ: 10.13 (s, 1H), 10.03 (s, 1H), 9.85 (s, 1H), 8.90 (s, 1H), 8.38-8.28 (m, 2H), 8.25 (d, J=2.6 Hz, 1H), 7.41 (dd, J=8.8, 2.6 Hz), 6.98 (d, J=8.8 Hz, 1H), 3.88 (s, 3H, 3.69 (dd, J=8.7, 5.6 Hz, 1H), 2.94-2.87 (m, 2H), 2.10-1.97 (m, 1H), 1.81-1.60 (m, 3H). LRMS (ESI, positive) m/e 357.1 (M+1).
