Procedure

To a solution of Example 100 (1.00 g, 2.18 mmol) in methanol (5 ml), lithium hydroxide (0.856 g, 20.40 mmol) in water (5 ml) and THF (19 ml) were added and stirred at RT. After 12 h, pH was adjusted to 7-7.5 using 0.5N HCl and the solid precipitated was filtered, washed with ethyl acetate and petroleum ether and dried under vacuum to afford the title compound as an off-white solid (0.900 g, 93%).
