Reaction Steps

To a suspension of 253 (422 mg, 1.21 mmol) in MeOH (15 ml) was added NaOH (145 mg, 3.63 mmol). The reaction mixture was heated at 60° C. during 16 h. Water (1 ml) was then added and the reaction mixture was stirred for 1 more hour. The solvent was evaporated and the residue was dissolved in water and acidified to pH 5 with HCl 1M. The precipitate was filtered to afford the desired compound 254 (348 mg, 95%) as a white solid. LRMS: 302.0 (Calc.). 303.0 (found).
