Reaction Steps
1-Ethyl-2-naphthalen-1-yl-1H-imidazole-4-carboxylic acid ethyl ester (2.2 g, 7.48 mmol) is dissolved in THF (20 ml), followed by the addition of aqueous lithium hydroxide solution (2.0 N, 7.5 ml, 2.0 eq.). The mixture is heated at 50° C. overnight. THF is stripped off under reduced pressure, and the residue is diluted with water (10 ml), basified to pH=4˜5. The solid precipitate is collected, washed with water and ether, dried under high vacuum to give the title compound. LCMS 267 (M+1).
