We demonstrated that the resulting catalyst is applicable to various aromatic and aliphatic amines giving excellent yields of the desired products in short reaction time ( UR - https://www.orgchemres.org/article_69578.html L1 - https://www.orgchemres.org/article_69578_6e25b0c54f69e1c9eb9134b47cba84ca.pdf ER -
