A mixture of 4-(biphenyl-4-yloxymethyl)-5-methyl-furan-2-carbonitrile (148) (100 mg, 0.35 mmoles), sodium azide (27 mg, 0.415 mmoles) and potassium carbonate (62 mg, 0.45 mmoles) in dimethylformamide (5 ml) was heated at 90° C. for 96 hours then at 120° C. for 24 hours. The mixture was evaporated and the residue purified by HPLC to afford compound 149 as a white solid (64 mg). LC/MS System D; Rt=9.53 mins, m/2 (ES+)=333 (M+H for C19H16N4O2).
