Procedure

To a solution of 2-(4-chloro-7-methylquinazolin-2-yl)phenol (2.84 g, 10.5 mmol) and azetidine-3-carboxylic acid (1.06 g, 10.5 mmol) in DMF (100 mL) was added triethylamine (3.18 g, 4.39 mL, 31.5 mmol). The reaction was stirred at room temperature overnight then diluted with H2O (400 mL). The pH of the solution was adjusted to 3-4 by addition of an aqueous 1 M HCl solution. The white precipitate then obtained was filtered, washed with H2O, and purified by silica gel chromatography using 0-15% MeOH—CH2Cl2 giving 1-(2-(2-hydroxyphenyl)-7-methylquinazolin-4-yl)azetidine-3-carboxylic acid. LC/MS: m/z 336.3 (M+H)+ at 1.97 min (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA)).
