Reaction Steps

Ethyl 2-(2,3-dihydro-1,4-oxathiin-6-yl)-2-n-hexyloxyiminoacetate (mixture of syn isomer and anti isomer, 186.8 g.), 1N aqueous solution of sodium hydroxide (472 ml.) and methanol (1.8 l.) were stirred at room temperature for 35 minutes and the insoluble substance was removed by filtration. The filtrate was stirred at room temperature for 43 hours and treated in a similar manner to that of Example I-(iii) to give 2-(2,3-dihydro-1,4-oxathiin-6-yl)-2-n-hexyloxyiminoacetic acid (syn isomer, 43 g.).
