4-[1-(4′-tert-Butyl-2,6-dimethyl-biphenyl-4-yloxy)-3-methyl-butyl]-benzoic acid (1.00 g, 2.25 mmol) and 2-chloro-4,6-dimethoxy-1,3,5-triazine (593 mg, 3.38 mmol) is stirred in THF (25 mL) under nitrogen. N-Methyl morpholine (0.37 mL, 3.38 mmol) is added followed by addition of aminoacetonitrile hydrochloride (229 mg, 2.48 mmol) and the mixture stirred at room temperature for 24 h. The reaction is filtered and the resulting filtrate concentrated and purified by silica gel chromatography, eluting with hexanes using a gradient of 0-100% ethyl acetate to provide 806 mg (74%) of the titled compound as a white solid. 1H NMR.
