Procedure

To a solution of methyl 4-(4-{5-[(4-fluorophenyl)methyl]-6-methylpyrimidin-4-yl}-2,3,4,5-tetrahydro-1,4-benzoxazepin-7-yl)benzoate (1.0 g, 2.0 mmol) in 1:1 methanol and THF (10 mL) was added drop wise 2N aqueous potassium hydroxide (8 mL). The reaction mixture was stirred at room temperature for 18 h and then refluxed for 90 min. The mixture was cooled by adding ice, and the pH adjusted to 6 with 2N aqueous hydrochloric acid. The precipitate was filtered, washed with water, azeotroped with toluene (20 mL), and dried to afford 4-(4-{5-[(4-fluorophenyl)methyl]-6-methylpyrimidin-4-yl}-2,3,4,5-tetrahydro-1,4-benzoxazepin-7-yl)benzoic acid (0.97 g, 100% yield).
