実験手順
To 2-methyl-N-(2-{[1-(phenylsulfonyl)-1H-indol-5-yl]oxy}ethyl)propanamide (Intermediate 37, 0.13 g, 0.33 mmol) in acetonitrile (200 mL) was phosphoryl chloride (2.5 mL) added and the reaction mixture was heated at reflux for 20 hours. The reaction mixture was evaporated to give the title compound (120 mg). MS m/z 369 [M+H]+.
