実験手順: A temperature of 59.8 g of a 28% solution of sodium methoxide in methanol was raised to 60° C., a mixture solution of 70.4 g of o-bromobenzyl bromide and 70.4 g of methanol was added dropwise, and this was retained at 60° C. for 2 hours. After the mixture was cooled to room temperature, 211 g of toluene and 211 g of water were added thereto, the mixture was stirred, and layers were separated, and an organic layer was recovered. An aqueous layer was extracted with 211 g of toluene three times, the recovered organic layer and 211 g of water were added, and this was washed, and concentrated to obtain 55.3 g of 1-methoxymethyl-2-bromobenzene. layers were separated an organic layer was recovered An aqueous layer was extracted with 211 g of toluene three times the recovered organic layer and 211 g of water were added this was washed concentrated

実験手順: 500 ml of an ethereal 1 M zinc chloride solution was dripped into a Grignard solution prepared from 12.0 g (0.46 mol) of magnesium shavings and 99.5 g (0.5 mol) of 1-bromo-2-methoxymethylbenzene in 500 ml of THF. The mixture was then refluxed for 1 hours, and a solution of 61.2 g (0.5 mol) of oxalic acid methyl ester chloride in 100 ml of THF was dripped in at an internal temperature of (-10)°C. After the mixture had been heated to about 20° C. it was stirred for a further 20 hours and then hydrolyzed with saturated ammonium chloride solution. After extraction with ether the combined ether phases were washed with water, dried and evaporated down. There was obtained 60 g of product (57.7%) as a mobile liquid. The mixture was then refluxed for 1 hours After extraction with ether the combined ether phases were washed with water dried evaporated down

実験手順: 685 g (2.74 mol) of o-bromobenzyl bromide was refluxed with 2.74 mol of a 30% strength sodium methylate solution in methanol for 15 hours. After the mixture had cooled to room temperature it was evaporated down, taken up in ethyl acetate, and washed with water. After the organic phase had been dried over sodium sulfate, it was again evaporated down. There was obtained 478.2 g (87%) of the title substance as a colorless liquid. was evaporated down washed with water After the organic phase had been dried over sodium sulfate, it was again evaporated down There was obtained 478.2 g (87%) of the title substance as a colorless liquid
