Procedure

Methyl [(6,7-dichloro-2-ethyl-1-oxo-2,3-dihydro-1H-inden-5-yl)oxy]acetate (15.8 gm., 0.05 mole) is suspended in dry tetrahydrofuran (100 ml.) containing triton-B (1 ml.). The suspension is stirred at ambient temperature and methyl vinyl ketone (5.02 gm., 0.072 mole) is added. The solution which becomes warm initially, is stirred at ambient temperature for 4 hours. Then, the stirring solution is treated with methyl vinyl ketone (0.3 ml.) and triton-B (0.6 ml.) every 4 hours for the next twenty hours.
