Reaction Conditions

Reaction Steps

To the intermediate from Step A (75 mg, 0.23 mmol) in a screw cap tube was added DCM (2 mL), Et3SiH (0.4 mL) and TFA (0.4 mL). The closed tube was then heated at 75° C. for 1.5 hours. The solution was cooled and concentrated. To the residue, which is a mixture of the title compound and methyl 4-[1-(2,5-dichlorophenyl)vinyl]benzoate (1/1), was added DCM (4 mL) and PtO2 (15 mg). The solution was stirred under a hydrogen atmosphere (balloon) for 3 hours. The hydrogen was purged and the solution filtered. The residue was purified by silica gel chromatography using a hexanes/ethyl acetate gradient to give the title compound LCMS1 4.19 min. (M+H)=309
