Vardenafil Dessulfonyl Kusachena;Vardenafil Related Compound (2-(2-Ethoxyphenyl)-5-methyl-7-propyl-3H-imidazo[5,1-f][1,2,4]triazin-4-one) Vagadziri

2-Amino-5-nitropyridine CAS 4214-76-0 inotorwa kubva kune nitration ye2-aminopyridine. Patembiricha ye50 °C, 2-aminopyridine yakawedzerwa kune yakanyungudutswa sulfuric acid, uyezve fuming nitric acid yakawedzerwa inodonha, uye tembiricha haina kudarika 50 °C. Gadzirisa pa45°C kwe2h, uye kurunga pakamuri tembiricha kwe4h. Mhinduro yekugadzirisa yakadururwa muchando chakapwanyika, uye pH yakagadziridzwa kusvika 6 nekuwedzera ammonia mvura pasi pe5 ° C, uye makristasi akaiswa. Sefa uye woomesa. Recrystallization nemvura kuti uwane yakacheneruka yero maplatelet, goho 75%

White crystal kana crystalline poda, isina kunhuwa, nekunaka kunotapira. Soluble mumvura (16.5%, 25â), isinganyunguriki mu ether kana acetone. Tembiricha yekuora ndeye 297â>, mp233â, isoelectric point 5.79, pka-COOH=2.34, Pka-NH3=9.60, [α]25D 14.Chemicalbook6 (C=0.5ï½2.0g/ml, 5mo LHCl). L-alanine isiri yakakosha amino acid mumuviri wemunhu, iyo inoumbwa nekuendesa amino boka re glycine kune pyruvic acid in vivo. Mune glucose-alanine kutenderera, yakaderera ropa ammonia mazinga anochengetwa. Alanine inotakura yakanakisa nitrogen muropa. Iyo zvakare inoshanda glycogenic amino acid. Kugamuchirwa kutenga L-Alanine CAS 56-41-7 kubva kwatiri.

Izvi zvinotevera kuunzwa kwemhando yepamusoro 5-Bromosalicylaldehyde CAS 1761-61-1, vachitarisira kukubatsira kunzwisisa zviri nani 5-Bromosalicylaldehyde CAS 1761-61-1. Tikugashirei vatengi vatsva uye vekare kuti varambe vachibatana nesu kugadzira ramangwana riri nani!
White filamentous makristasi. Melting point 102-105 â.

Sekugadzira nyanzvi, tinoda kukupa mhando yepamusoro 3',5'-Bis(trifluoromethyl)acetophenone CAS 30071-93-3. Uye isu tichakupa iwe yakanakisa mushure mekutengesa sevhisi uye kuendesa panguva.

Senyanzvi yekugadzira, tinoda kukupa mhando yepamusoro (Z) -2-((3S,5R)-3,5-bis((tert-butyldiMethylsilyl)oxy)-2-Methylenecyclohexylidene)ethanol CAS 81506-24- 3. Uye isu tichakupa iwe yakanakisa mushure mekutengesa sevhisi uye kuendesa panguva.
