実験手順

322.5 g of methyl 3-methyl-6-(phenylthio)-benzoate in 3 litres of absolute tetrahydrofuran are treated dropwise over a period of 30 minutes under argon and under reflux with 420 ml of a 70% sodium-dihydro-bis(2-methoxyethoxy)-aluminate solution in benzene and the mixture is boiled for a further 3 hours under reflux. Then the mixture is cooled to ca 4° C, diluted with 1 litre of benzene, hydrolysed with 700 ml of 2-N hydrochloric acid, then poured on to ice-water and treated with a further 400 ml of concentrated hydrochloric acid in order to obtain a clear solution. The organic phase is washed with water, dried over sodium sulphate, filtered and evaporated. There is obtained 3-methyl-6-(phenylthio)-benzyl alcohol as a red-brown oil.
