Procedure

N-(3,5-dichloropyrid-4-yl)-4-methoxy-8-amino dibenzo[b,d]furan-1-carboxamide (500 mg, 1.24 mmol) was suspended in ethanol and a 50% solution of ethyl glyoxalate in toluene (384 mg, 3.72 mmol) was added to the suspension. The reaction mixture was hydrogenated at 40 psi in presence of pre-activated raney nickel (50% w/w) for 24 h-48 h. The reaction was filtered and the filterate was concentrated in vacuo. The residue was purified by silica gel (100-200) column chromatography using 0.5% methanol in dichloromethane to obtain the compound as a pale yellow solid (180 mg). mp: >270° C.
