In the title compound, C(21)H(23)N(5)O(2), the conformation about the imine bond [1.287 (3) Å] is E. Overall, the mol-ecule has a disk shape, the dihedral angles between the imidazole ring and the meth-oxy-phenyl and methyl-phenyl rings being 49.42 (13) and 42.62 (13)°, respectively; the dihedral angle between the benzene rings is 20.11 (11)°. In the urea moiety, the N-H atoms are anti to each ...

Bu çalışmada önce literatürde bulunan yöntemle maleik anhidrit (mal) ile sülfanilamitin (sa) tepkimesinden sülfanilamit içeren asit olan (E)-3-(4-sülfamoilfenilkarbamoil) akrilik (1) sentezlenmiştir. Daha sonra 1 2-amino-6-metilpiridin (2), 2-amino-5-metilpiridin (3), 2-amino-4-metilpiridin (4) ve 3-aminopiridin (5) proton transfer tuzları (6-9) elde edilmiştir. Elde edilen tuzların yapıları, e...
