The synthesis and reaction of 2-Chloro-4-phenyl-6-p-tolyl- nicotinonitrile (I) with hydrazine hydrate, sodium azide and urea to give the corresponding hydrazino tetrazolopyridine and urea derivatives respectively, are studied. The reaction of (I) with compounds containing active methylene group is reported. The mode of formation and structure of the various products are also discussed.يتناول هذا البحث تخليق وتفاعل مركب 2 - كلورو- 4-فينيل - 6 - بارا - طوليل - نيكوتينونيتريل ( I ) مع هيدرات الهيدرازين ، أزيد الصوديوم ، واليوريا ليعطي مشتقات الهيدرازينو ، التيترازولوبيريدين واليوريا ، على التوالي ، كذلك فإن هذا البحث يتضمن تفاعل المركب (I) مع مركبات تحتوي على مجموعة مثيلين منشطة ، ويناقش سبل تكوين وأشكال المركبات الناتجة من هذه التفاعلات
