8020 g (65.44 mol) of ethyl chloroacetate are added to a mixture of 62 l of acetonitrile, 9490 g (62.38 mol) of methyl salicylate, 8610 g (62.38 mol) of potassium carbonate and 620 g of potassium iodide at 20° C., and the mixture is stirred and heated under reflux for 9 hours and stirred overnight without further heat being supplied. The mixture is filtered over Celite and the filtrate is concentrated under reduced pressure. 16.4 kg of methyl 2-ethoxycarbonylmethoxybenzoate are obtained (HPLC: logP=2.1)
