Stage 3: Preparation of 4-f2,6-dichlorobenzoylamino)-l\/\/-pyrazole-3-carboxylic acid methyl ester EPO C12H9CI2N3O3 FW: 314.13A solution of 4-amino-l\/\/-pyrazole-3-carboxylic acid methyl ester (0.634 Kg, 4.49 mol, 1 wt) in 1,4-dioxane (8.90 L, 9 vol) under nitrogen was treated with triethylamine (0.761 L, 5.46 mol, 1.2 vol) followed by 2,6-dichlorobenzoyl chloride (0.710 L, 4.96 mol, 0.72 vol) such that the internal temperature was maintained in the range 20 to 25 0C. Residual 2,6-dichlorobenzoyl chloride was washed in with a line rinse of 1 ,4-dioxane (0.990 L, 1 vol) and the reaction mixture stirred at 18 to 25 C until complete (16 hours) by TLC analysis (eluent: ethyl acetate: heptanes 3:1; Rf amine 0.25, Rf product 0.65). The reaction mixture was filtered, the filter-cake washed with 1,4-dioxane (2x 0.990 L, 2x 1 vol) and the combined filtrates (red) progressed to Stage 4 without further isolation.<\/p>\n
