Procedure

A solution of the amine 4 (1.0 mg, 1.9 μmol, 1.0 equiv) in dichloromethane (0.1 mL) was added to 7-methylquinoline-2-carboxylic acid (2.8 μmol, 1.5 equiv) and 1-hydroxybenzotriazole (0.44 mg, 3.2 μmol, 1.7 equiv) in a vial at 23° C. The solution was stirred for 5 min, then N-cyclohexylcarbodiimide-N′-propyloxymethyl polystyrene (Argonaut Technologies, 1.13 mmol/g, 3.4 mg, 3.8 μmol, 2.0 equiv) was added in one portion at 23° C. The reaction mixture was stirred gently at 23° C. under an argon atmosphere for 16 h. PS-Trisamine (Argonaut Technologies, 4.71 mmol/g, 2.0 mg, 9.5 μmol, 5.0 equiv) was then added in one portion and the reaction mixture was stirred for a further 2 h. The mixture was filtered through Celite (0.5 cm) and concentrated in vacuo to give the 7-methylquinoline-2-carboxylic acid amide derivative (1.2 mg, 95%) as an off-white solid.
