Ethanol → HCID 20095020, compound

Participants

Reaction Steps

5.00 g (20.3 mM) of 2-hexylindan-5-boronic acid, 2.79 g (17.8 mM) of 6-chloronicotinamide, 20 ml of ethanol, 30 ml of benzene, 27.9 ml of 2M-sodium carbonate aqueous solution and 1.19 g of tetrakis (triphenylphosphine) palladium (O) were mixed and heat-refluxed for 2 hours under stirring. After the reaction, the reaction mixture was poured into water to obtain an insoluble matter. The insoluble matter was recovered by filtration. Separately, the filtrate was subjected to vacuum distillation to remove the organic solvent and poured into water to obtain an insoluble matter. The insoluble matter was added to the above-prepared insoluble matter. To the resultant mixture, 100 ml of acetone was added, followed by cooling with ice to precipitate a crystal. The crystal was recovered by filtration and washed with acetone, followed by drying to obtain 5.30 g of 2-hexyl-5-(5-carbamoylpyridine-2-yl)indan (Yield: 92.2%).
