Versuchsvorschrift

Following the procedure described in Reference Example 1-1, 3-methyl-1-(6-ethoxy-2-pyridinyl)-1H-pyrazol-5-amine was prepared from aminocrotononitrile and 6-ethoxy-2-hydrazinopyridine. Following the procedure described in Reference Example 1-2, the compound was subjected to a reaction with ethyl 2-benzoyl-3-ethoxy-2-propenoate to give ethyl 2-benzoyl-3-[[3-methyl-1-(6-ethoxy-2-pyridinyl)-1H-pyrazol-5-yl]amino)-2-propenoate. The compound was treated following the method described in Example 1-4 to give the title compound (35% cyclization yield).
