Procedure
1.3 g of N-(2-aminobenzoyl)-N'-[4-(5-bromo-2-pyrimidinyloxy)-3-methylphenyl]urea (Compound No. 27 as described hereinafter) as prepared in accordance with Preparation Example 3, was added to 30 ml of pyridine, and 0.25 ml of acetyl chloride was dropwise added thereto under cooling with ice. The mixture was stirred at room temperature for 2 hours and 30 minutes. Then, pyridine was distilled off, and the residue was purified by silica gel column chromatography (developing solvent; methylene chloride:ethyl acetate=7:3) to obtain 1.18 g of the desired product (melting point: 186°-191° C.) (Compound No. 49 as described hereinafter).
