Participants

Reaction Steps

Following General Procedure A, 1.0 g (7.2 mmol) of 3-butyl-5-methyl-1H-1,2,4-triazole was reacted with 2.89 g (9.5 mmol) of the alkylating reagent prepared in step 1 of Example 1. Hydrolysis of the slower moving isomer provided 220 mg of 4′-[(3-butyl-5-methyl-1H-1,2,4-triazol-1-yl)methyl][1,1′-biphenyl]-2-carboxylic acid as a colorless solid: NMR (DMSO-d6) δ 0.88 (t, J=7 Hz, 3H), 1.25–1.38 (m, 2H), 1.54–1.67 (m, 2H), 2.39 (s, 3H), 2.54 (t, J=8 Hz, 2H), 5.32 (s, 2H), 7.21 (d, J=8 Hz, 2H), 7.32 (d, J=8 Hz, 2H), 7.36 (dd, J=8 and 2 Hz, 1H), 7.46 (dt, J=8 and 2 Hz, 1H), 7.56 (dt, J=8 and 2 Hz, 1H), 7.72 (dd, J=8 and 2 Hz, 1H).
