In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Synthesis of new proton-pump inhibitors, published in 1996-06-30, which mentions a compound: 84547-64-8, Name is 3-(Chloromethyl)-1-methyl-1H-pyrazole, Molecular C5H7ClN2, Category: amides-buliding-blocks.
For development new anti-ulcer agents, we synthesized omeprazole analogs, in which pyridine group was replaced by pyrazole moiety, to increase pharmacol. activity and to decrease side effects, and also synthesize substituted benzimidazole rings.
This compound(3-(Chloromethyl)-1-methyl-1H-pyrazole)Category: amides-buliding-blocks was discussed at the molecular level, the effects of temperature and reaction time on the properties of the compound were discussed, and the optimum reaction conditions were selected.
