HCID 194349916,8-difluoro-2-(3-fluoro-4-pivaloylaminophenyl)-5-(1-heptylamino)-7-methyl-4H-1-benzopyran-4-oneYield 46%

Procedure

Substantially the same manner as that in Example 107 (2) was repeated except that 650 mg (1.61 mmol) of 5-amino-6,8-difluoro-2-(3-fluoro-4-pivaloylaminophenyl)-7-methyl-4H-1-benzopyran-4-one obtained in Example 107 (1) and 0.53 mL (3.22 mol) of 1-iodoheptane were used, to give 369 mg of 6,8-difluoro-2-(3-fluoro-4-pivaloylaminophenyl)-5-(1-heptylamino)-7-methyl-4H-1-benzopyran-4-one (yield: 46%).
