Procedure

9-(N-Methylcarbamoyloxy)xanthene (6.0 g., 23.5 mmoles) was stirred with 15 ml. of 2-buten -1-ol for 1.5 hours at room temperature, and the mixture was then filtered. The filtrate was evaporated in vacuo, and the residue was dissolved in ice-cold ether and washed twice with ice-cold portions of 10% aqueous acetic acid, water and 5% aqueous sodium bicarbonate solution. After drying over potassium carbonate, the solvent was removed in vacuo, and the resulting oil was distilled to give 2-buten-1-yl 9-xanthenyl ether, b.p. ca. 110°C. at 0.01 mm.
