Versuchsvorschrift

27.3 g of morpholine are added in a single portion to a solution of 30 g of 2,3-dihydro-2-benzofuranone in 100 ml of ethanol, and the medium is stirred for 1 hour. The solvent is evaporated off under vacuum, the residual gum is taken up in isopropyl ether in the hot state and the medium is allowed to return to room temperature. The crystallized product is filtered, washed with isopropyl ether and dried. 45 g of white crystallized product are obtained.
