Reaction Steps

2-(2-aminothiazole-4-yl)-2-acetoxyiminoacetic acid dihydrate (syn-isomer) (20.0 g) was suspended in acetone (200 ml) and stirred, and heated and refluxed at 55 to 56° C. for one hour. After the mixture was cooled to 5° C., the crystal was filtered and washed with acetone, and dried under reduced pressure to obtain 2-(2-aminothiazole-4-yl)-2-acetoxyiminoacetic acid anhydrous crystal (16.4 g).
