Reaction Conditions

Reaction Steps

To a stirring solution of compound 119 (0.856 g, 3.11 mmol) in ethanol (16 mL) and THF (8 mL) was added an aqueous solution of sodium hydroxide (5 mL, 31.3 mmol) and the resulting mixture was stirred at 55° C. for 2 h. The reaction mixture was solvent evaporated to one third volume, acidified with 3N HCl to pH 2 and the resulting white precipitate was filtered to afford 120 (0.801 g, 99%) as a beige solid. LRMS (ESI): (calc) 261.01 (found) 262.1 (MH)+.
