実験手順

150 mg (0.31 mmol) of (S)-N-(1-(4-(2-acetyl-1-methyl-1H-imidazol-4-yl)phenyl)-4-hydroxybutan-2-yl)-3-chloro-4-isopropoxybenzamide in 2 mL of benzene was treated with 34.6 uL (0.62 mmol) of ethane-1,2-diol and 59 mg (0.31 mmol) of p-toluenesulfonic acid monohydrate. The reaction was stirred at 70° C. for 2 h after which the solvents were evaporated and the residue purified via reverse phase HPLC (acetonitrile/water). 25.5 mg (16% yield) of 4 was obtained and characterized by LCMS and HNMR.
