6-Chloro-N-[1-naphthalen-2yl-ethyl]-[1,3,5]triazine-2,4-diamine (30 mg, 0.1 mmol), 2-boc-protected amino-3-{3-[4,4,5,5,-tetramethyl-[1,3,2]dioxaborolan-2-yl)-pyrazol-1-yl]-propionic acid (50 mg, 0.15 mmol), 1 ml of acetonitrile, and 0.7 ml of water. Aqueous sodium carbonate (0.3 ml and 1N) was added to a microwave vial, followed by 5 mol percent of dichlorobis(triphenylphosphine)-palladium(II). The reaction vessel was sealed and heated to 150° C. for 5 minutes with microwave. After cooling, the reaction mixture was evaporated to dryness, the residue was dissolved in 2.5 ml of methanol, and then was purified with Prep-LC to give 6.8 mg of boc protected 2-amino-3-{3-[4-amino-6-(1-naphthalen-2-yl-ethylamino)[1,3,5]triazin-2-yl]-pyrazol-1-yl}proionic acid.
