Procedure

step 3—A solution of 324 (93 mg, 0.162 mmol) in MeOH (10 mL) and sodium methoxide (10 mL, 5 mmol, 0.5 M methanol solution) was stirred at RT overnight. The reaction mixture was concentrated, diluted with EtOAc and acidified with 6N HCl (1 mL). The organic extract was dried (Na2SO4), filtered and concentrated. The crude product was purified on a preparative TLC plate developed with 2:1 EtOAc/hexane to afford 26 mg (31%) of I-209 as an off-white solid.
