実験手順
Reaction and post treatment were carried out in the same manner as in Example 6-(c) except for using 3.40 g (3.13 mmol) of 2-(3-cyclopropoxy-4-difluoromethoxyphenyl)-3-cyclopropylmethyl-5-(2-trimethylsilylethoxymethyl)-1,5-dihydropyrrolo[2,3-d]pyridazin-4-one obtained in Example 15-(d) in place of 2-(3-cyclopropoxy-4-difluoromethoxyphenyl)-3-propyl-5-(2-trimethylsilylethoxymethyl)-1,5-dihydropyrrolo[2,3-d]pyridazin-4-one, whereby 2.50 g of the title compound was obtained as a white solid.
