Reaction Steps

A solution of the product from Step A (14.2 g, 82 mmol) in 1,2-dichlorobenzene (90 mL) was fluxed for 6 h and the reaction mixture was evaporated to a residue which was purified by chromatography (silica, EtOAc) to give a tan solid (8.59 g, 60%) that was used in the next step: LC/MS (+APCI) m/z 175 (M+H).
