METHOD OF PREPARING FOR HETEROCYCLIC COMPOUNDS HAVIN FUNGICIDAL HERBICIDAL AND PALNT-GROWTH REGULATING PROPERTIES

摘要

The title compds. I (R1,R2=optionally substituted aromatic ring contg. 1-2 N. ph; R3=acyl; R4=H, C1˜C4 alkyl) were prepd. Thus, 18.3g 3-(3'-pyridylaminomethyl)pyridine in 50mL toluene was refluxed with 98% formic acid to give 27% 3-(3'-pyridylmethyl)amino-pyridine, which was added to a soln. contg. 2.8g trimethylacetylchloride and treated with 2.6g triethylamine to give 65% N-t-butylcarbonyl-3(3'-pyridylmethyl)aminopyridine.
