Reaction Steps

To a solution of 4-chloro-7-iodo-8-phenyl-1-(2-trimethylsilanyl-ethoxymethyl)-1H-chromeno[7,8-d]imidazol-6-one and 4-chloro-7-iodo-8-phenyl-3-(2-trimethylsilanyl-ethoxymethyl)-3H-chromeno[7,8-d]imidazol-6-one (80 mg, 0.14 mmol) in DCM (4 mL) was added TFA (1.0 mL) at RT. After 18 h, the reaction mixture was evaporated to dryness. The crude residue was triturated with DCM and concentrated in vacuo to afford the title compound as a white solid (59 mg, 100%). LCMS (Method A): RT=4.38 min, [M+H]+=423/425.
