A mixture of 6-((6-bromo-1H-[1,2,3]triazolo[4,5-b]pyrazin-1-yl)methyl)quinoline, (350 mg, 1.03 mmol), potassium carbonate (436 mg, 3.16 mmol), and 3-pyrrolidine carboxylic acid (236 mg, 2.05 mmol) in n-butanol (10.0 mL) was heated in the microwave at 120° C. for 60 minutes. The reaction mixture was cooled to room temperature, filtered, rinsed with ethyl acetate, and the filtrate was concentrated. The crude product was purified by flash chromatography using a Horizon purification system on a 25S column eluting with chloroform containing 0.1% acetic acid/methanol (0.5-7%) to afford 1-[1-(quinolin-6-ylmethyl)-1H-[1,2,3]triazolo[4,5-b]pyrazin-6-yl]pyrrolidine-3-carboxylic acid (152 mg, 39%).
