The previous study has reported the synthesis of N,N-bis-(2-hydroxyethyl)-p-methoxycinnamamide (2) by using microwave-assisted direct amidation of EPMC (1) with diethanolamine. In this research, we attempt to synthesize of 2 by using a conventional direct amidation of EPMC (1) with diethanolamine. The reaction was conducted without adding any coupling reagents or catalyst. Structure of the synthetic product was determined by using analysis of GC-MS, IR, and 1H-NMR spectroscopic data and then compared to the previously reported. date: 2018 publisher: UIN Jakarta full_text_status: public publication: valensi volume: 4 number: 1 pagerange: 22-25 refereed: TRUE citation: Supandi Supandi, Supandi (2018) Direct Amidation of ethyl p-methoxycinnamate to Produce N,N-bis-(2-hydroxyethyl)-p-methoxycinnamamide. valensi, 4 (1). pp. 22-25. document_url: http://repository.uhamka.ac.id/id/eprint/8538/1/7300-22025-4-PB.pdf
