Reaction Steps
A mixture of 1.2 g of 4-chloro-3-hydroxy-9-oxo-9H-xanthene, 1.7 g of postassium carbonate, 2.1 g of ethyl bromoacetate and 30 ml of DMF was stirred at 60°-70° C. for 3 hours. After cooling the mixture, water was added and the resulting crystal was recovered by filtration, washed with water and dried. Recrystallization from ethanol gave 1.1 g of ethyl 4-chloro-9-oxo-9H-xanthene-3-yloxyacetate. m.p. 183°-185° C.
