Sodium Hydroxide → Indoline

Participants

Reaction Steps

Into a 100 ml reaction flask equipped with a condenser, a thermometer and a stirrer, 15.56 g (0.1 mol) of 2-chlorophenethylamine, 22.0 g (0.11 mol) of a 20% sodium hydroxide aqueous solution and 0.176 g (0.5 mol %) of quinoline copper were charged, and reacted at 110° C. for 8 hours. The reaction mixture thereby obtained was subjected to liquid separation to separate the aqueous layer from the organic layer. The organic layer was washed with an acid and distilled to obtain 11.4 g of indoline (boiling point: 94°-95° C./11 mmHg). The purity was 99.5%, and the yield was 96%.
