Reaction Steps

A mixture of methyl methoxylacetate (15 ml, 1.0 eq) and ethyl formate (12.18 ml, 1.0 eq) was added dropwise to slurry of sodium methoxide (8.17 g, 1.0 eq) in toluene (100 ml) at ice both. After dropping at room temperature and stirring overnight, the resulting solution was dried in vacuo. Then a mixture of residue, urea (9.09 g, 1.0 eq) and NaOMe (4.10 g, 0.5 eq) in EtOH (100 ml) was refluxed at 110° C. for 4 hrs. After the solvent was dried in vacuo, water and conc. HCl solution (5<pH<4) were added. After formation of white precipitate, the mixture was filtered and dried solid in vacuo. A product was obtained as a white solid (5.14 g, 23.88%)
