Triethylamine → (1-pyrrolidin-1-ylindan-5-yl)propynoic Acid

関与物質

反応手順

Under an argon atmosphere at 0° C., 0.5 g (1.59 mmol) of 1-(5-iodoindan-1-yl)pyrrolidine and 123 mL (2 mmol) of propynoic acid are dissolved in 25 mL of acetonitrile. 0.66 mL (4.79 mmol) of triethylamine, 30 mg (0.16 mmol) of copper (I) iodide, and 80 mg (0.11 mmol) of ditriphenylphosphine palladium dichloride are added to this solution and the mixture is stirred for 2 hours, while the solution is allowed to come up to ambient temperature. The purification is carried out by preparative HPLC (eluant: dichloromethane/methanol/ammonia (8:2:0.2)). Yield 0.1 g (24.5% of theory); C16H17NO2 (M=255.31); calc.: molecular ion peak (M+H)+: 256; found: molecular ion peak (M+H)+: 256.
