Reaction Steps

5-(Isobutyryl-methyl-amino)-4′-methyl-biphenyl-3-carboxylic acid methyl ester (67 mg, 0.22 mmol) was added to methylene chloride (3 mL) and stirred at room temperature. TEA (0.87 g), 1-pyrazin-2-yl-ethylamine (32 mg, 0.25 mmol), HOBt (29 mg) and ECDI (54 mg) were added, and the reaction mixture was stirred overnight at room temperature. The reaction mixture was placed directly onto a silica column and eluted with 50% ethyl acetate/hexanes to give 32 mg of 5-(isobutyryl-methyl-amino)-4′-methyl-biphenyl-3-carboxylic acid (1-pyrazin-2-yl-ethyl)-amide as a white solid, MS (M+H)=417.
