Reaction Steps

A mixture of ethyl 2-((1,1′-biphenyl)-4-ylamino)-6-oxo-1,6-dihydropyrimidine-5-carboxylate (100 mg, 0.298 mmol), sodium hydroxide (1M, aq), and methanol was stirred at 70° C. for 2 hours and for 40° C. overnight. The ester did not dissolve in 3 mL methanol. The ester was then put in 3 mL dioxane and heated to 103° C. for 4 hours with an additional 1 mL of NaOH added. The reaction mixture was then heated at 40° C. overnight. After the overnight heating, the reaction mixture was cooled and the solvent removed. The reaction mixture was diluted with water, and the pH was adjusted to about 3.0. The reaction mixture was filtered to obtain the end product. 1H-NMR confirmed the product (55 mg, 60.0% yield).
