This method has several advantages, such as efficiency, good yield, short reaction time, cleaner reaction profiles, ease of product isolation, operational simplicity and inexpensive, effective and catalyst.}, keywords = {Naphtho[1′,2′:5,6]pyrano[2,3-d]pyrimidine,Aldehyde,β-Naphthol,6-Amino-1,3-dimethyl uracil,Formic acid}, url = {https://www.orgchemres.org/article_63248.html}, eprint = {https://www.orgchemres.org/article_63248_5aed1b63a555d775861591a33de33010.pdf} }
