実験手順

Under ice-cooling and N2 atmosphere, a solution of 1.47 g of 2-thiophenecarbonyl chloride in 10 ml of methylene chloride is added to a mixture of 2.91 g of 4-amino-2,6-diisopropylphenol hydrochloride, 90 ml of ethyl acetate, 80 ml of water, and 8.0 g of sodium hydrogen carbonate during a period of 30 minutes. After stirring at room temperature for one hour, organic layer is separated, washed with water, 10 % HCl, water, dried, and concentrated. The obtained solid is recrystallized from chloroform-hexane to give 1.7 g of 4-(2-thienylcarbonyl)-amino-2,6-diisopropylphenol.
