Reaktionsschritte
A three-necked flask is charged with 17 g of lithium aluminum hydride dissolved in anhydrous ethyl ether. 3 g of 2,3-dihydro-2-benzofurancarboxylic acid (Chim. Ler., (1973), 3, p. 259), dissolved in 1,140 ml of ethyl ether, are then introduced. The reaction medium is left stirring overnight. It is then hydrolyzed in an ice bath with 15.2 ml of water, 15.2 ml of 4N sodium hydroxide and then 45.2 ml of water. The complex is drained and washed with ethyl ether and the filtrate is dried and distilled to obtain the expected compound
