3-クロロ-N-(4-メトキシフェニル)-2-ニトロソアニリンの製造
前述のように、特開2018-70520(特許文献3)の方法においては、2-クロロニトロベンゼンの反応は低温を必要としている。比較例9では、そのような低温を避けて、当該反応の温度を25~30℃に変更して、特開2018-70520(特許文献3)の方法を行った。その結果、下記のように低い収率を与えた。特開2018-70520(特許文献3)の方法では、そのような低温を回避できなかった。
反応混合物のHPLC分析(面積百分率;254nm)の結果、反応混合物中の溶媒等を除く主な成分は以下の通りであった;
3-クロロ-N-(4-メトキシフェニル)-2-ニトロソアニリン(目的生成物):23.4%、
OCNB(原料):0.9%、
p-アニシジン(原料):N.D
MNA(副生成物;Cl置換体(脱Cl体)):34.5%、
CMNA(副生成物;目的生成物のニトロ体):2.1%、
3-クロロ-N-(4-メトキシフェニル)-2-ニトロソアニリン(目的生成物):31.0%(収率)、
OCNB(原料):3.8%(回収率)、
MNA(副生成物;Cl置換体(脱Cl体)):34.8%。
3-クロロ-N-(4-メトキシフェニル)-2-ニトロソアニリンの製造
3級アルコール(tert-ブタノール)の代わりに2級アルコール(2-プロパノール、すなわち、2-プロパノール)を用いた以外は、実施例5と同様にして反応と分析を行った。
比較例5~8に示すように、先行技術の方法を除草剤フェンキノトリオンの置換基の組み合わせを有する原料に適用しても、反応は十分には進行しなかった。要するに、先行技術は、除草剤フェンキノトリオンの製造に適用できないことが確認された。
例えば、比較例8に示すように、極端な低温を必要とせずにニトロソ化合物を製造できる先行技術は、除草剤フェンキノトリオンの製造に適用したときに、満足な収率を与えなかった。
