Procedure
A mixture of indoline (5.39 g) and cyclohexane-1,3-dione (5.07 g) was heated at ca. 150° for 7 h. After cooling, the mixture was purified by FCC eluting with ethyl acetate: methanol (10:1) to give a solid (7.30 g) which was recrystallised from ethyl acetate: ether (ca. 4:1) to give the title compound (5.08 g), m.p. 85°-86°.
