With caesium carbonate; In N,N-dimethyl-formamide; at 20℃; for 1h; | To a suspension of 9H-<strong>[82-07-5]xanthene-9-carboxylic acid</strong> (20 g, 88.4 mmol) and Cs2CO3 (34.5 g, 106 mmol) in dimethyl formamide (300 mL), methyl iodide (8.3 mL, 133 mmol) is added dropwise at RT. The reaction is stirred for 1h before it is quenched with water and extracted with diethyl ether. The organic phase is washed twice with water and with brine, dried over Na2SO4, filtered and evaporated to yield the title compound as a yellow solid. TLC, Rf (hexane/ethyl acetate 2/1) = 0.72. |
