Embodiment 1
[0054] Preparation of N'-(2-methylphenyl)-3-(uracil-5-sulfonamido)phenylurea A1.
[0055] a. Preparation of uracil-5-sulfonyl chloride: at 25-40°C, add uracil (5g, 44.63mmoL) and thionyl chloride (15ml, 89.26mmoL) into a 100mL reaction flask, activate 1.5-3 Add chlorosulfonic acid (25g, 133.89mmoL) to react at 50-65°C for 4-5h, and continue to react at 70-90°C for 5-8h; add the reaction solution into ice water, precipitate out, suction filter, wash with water for 50 C and dried to obtain 4.50 g of white solid, yield: 70%.
[0056] b. Dissolve 3-nitrobenzohydrazide (5.00g, 27.60mmol) in dichloromethane in a 100mL reaction flask at 0°C, and then add sodium nitrite (3.81g, 55.20mmol) aqueous solution Diluted hydrochloric acid (2.01g, 55.20mmol) was added dropwise, reacted for about 1-2 hours, separated and dried at 50°C to obtain 3-nitrobenzoyl azide yellow solid (5.00g, 26.05mmol), yield 94.28%.
