Versuchsvorschrift

199 g. (1mole) of 6-methyl-1,2,3,4-tetrahydrocarbazol-1-one dissolved in 2000 ml. of dimethylformamide are taken initially and 5.6 g. (0.1 mole) of potassium chloride dissolved in 200 ml. of water are added. Thereafter 66.1 g.=74.2 ml. (1.5 mole) of ethyleneoxide are added at room temperature and heated up to 50° C. within 30 minutes, a maximum pressure of 0.2 to 0.5 bar being generated. Stirring is done for 20 hours at 50° C., the solvent is distilled off in a vacuum and, the residue is stirred with a mixture of 800 ml. water and 10 ml. of glacial acetic acid; the product (which takes a crystalline form) is filtered with suction, washed with 500 ml. water and dried at 40° C. in vacuo.
