実験手順
Methyl 4-[5-(4-pentyloxyphenyl)isoxazol-3-yl]benzoate (16.4 kg), tetrahydrofuran (164 L), methanol (25 L) and 19% aqueous potassium hydroxide (25 L) were put into a 1500 L glass-lined reaction chamber, heated to 50 to 60° C., and stirred for 2 hours. Tetrahydrofuran (328 L) was added to this reaction mixture for 30 minutes to 1 hour. The mixture was then cooled to 35 to 40° C. and stirred further for 1 hour. The product was isolated by a centrifugal separator and washed with tetrahydrofuran (164 L) to obtain rough potassium 4-[5-(4-pentyloxyphenyl)isoxazol-3-yl]benzoate (which was used in the next step in a wet state).
