実施例1
2,6−ビス[1−(5−クロロ−2−メチルフェニルイミノ)−エチル]−ピリジン
25mlの丸底フラスコに、3gの2,6−ジアセチルピリジン(FW 163.13、18.4ミリモル)および100mlのトルエンを入れた。次に、数ミリグラムのp−トルエンスルホン酸を加え、続いて、7.81gの5−クロロ−2−メチル−アニリン(FW 141.60、55.2ミリモル)を加えた。この反応混合物を、2日間に亘りディーン・スターク・トラップで環流させながら加熱し、次いで、室温まで冷却した。NaHCO3で中和した後、その混合物を水で洗浄し、分離漏斗を用いて有機層を分離した。Na2SO4を用いてトルエン溶液を乾燥させ、その溶媒を蒸留によって除去した。残留物をEtOHから再結晶化させて、薄黄色の結晶5.88g(78%の収率)を得た。この生成物にGC/MS分析を行った:
MS m/e (%) 411(39), 410(36), 409(57), 397(20), 396(70), 395(54), 394(100), 284(13), 244(15), 243(15), 229(16), 166(23), 131(14), 125(32), 89(26)
この化合物の質量スペクトルが図1に与えられている。さらに、1Hおよび13C NMRスペクトルを収集した:
1H NMR (ppm, CDCl3) 8.36 (d, 2H), 7.91 (t, IH), 7.19 (d, 2H), 6.99 (d, 2H), 6.69 (d, 2H), 2.32 (s, 6H), 2.11 (s, 6H)
