실험 절차

To a solution of 1-(diphenylmethyl)-3-(5-hydroxy-2,3-dihydro-1-benzofuran-6-yl)-1,3-dihydro-2H-indol-2-one (1.01 g, 2.30 mmol) in THF (50.0 mL) was added paraformaldehyde (1.00 g, 30.0 mmol). Argon was bubbled through the reaction mixture for one hour followed by the addition of diisopropylamine (1.00 g, 10.0 mmol) at 0° C. The reaction mixture was stirred at ambient temperature for 20 hours and diluted with ethyl acetate (100 mL). The resulting mixture was washed with water (2×50.0 mL), dried over sodium sulfate and filtered. The filtrate was concentrated in vacuo to dryness to give 0.67 g (65%) of the title compound: MS (ES+) m/z 486.4 (M+23).
