実験手順

H2S gas was passed slowly through a solution of methyl 2-(5-{3-[5-cyano-2-pyridinyl)oxy]propoxy}-1H-indol-1-yl)propanoate (Example 67, 0.50 g, 1.32 mmol) in DMF (7.80 mL) for 20 minutes at rt. Diethylamine (0.21 mL, 2.37 mmol) was added in one portion, and the resultant light green solution was heated at 60° C. for 3 h. The reaction mixture was purged with a stream of argon, and then concentrated under reduced pressure. The desired compound (0.49 g, 90%) was isolated by column chromatography (50% hexanes in EtOAc) as a bright yellow solid. 1H NMR (400 MHz, CD2Cl2) δ 8.63 (dd, 1H), 8.16 (dd, 1H), 7.25-7.08 (m, 3H), 6.86-6.74 (m, 2H), 6.46 (d, 1H), 5.16 (qt, 1H), 4.59 (t, 2H), 4.17 (t, 2H), 3.71 (s, 3H), 2.35-2.25 (m, 2H), 1.82 (d, 3H).
