Procedure

To a mixture of 4-5 g. of solid potassium t-butoxide in 464 g. (4.0 mole) of indene heated to 120° is added dropwise over 11/2 hours 256 g. (2.0 mole) of n-butyl acrylate at 100°-120°. After 1 hour longer at 120°-150°, the mixture is cooled, treated with 25 ml. acetic acid and filtered. Distillation affords 256 g. (57%) of product collected at 143°-160° (2 mm. torr.).
