Procedure

HCl in dioxane (4.0 M, 1 mL) was added to tert-butyl 4-fluoro-3-oxo-1′H,3H-spiro[furo[3,4-c]pyridine-1,3′-pyrrolidine]-1′-carboxylate (25.8 mg, 0.0000837 mol). The reaction mixture was stirred at room temperature for 30 minutes before the volatiles was removed to afford the free amine (hydrochloric acid salt), which was subsequently used in the coupling reaction. 4-Methylmorpholine (50 μL, 0.0004 mol) was added to a mixture of 1-quinolin-4-ylcyclopropanecarboxylic acid (17.8 mg, 0.0000837 mol), 4-fluoro-3H-spiro[furo[3,4-c]pyridine-1,3′-pyrrolidin]-3-one dihydrochloride (23.5 mg, 0.0000837 mol), and (benzotriazol-1-yloxy)tripyrrolidinophosphonium hexafluorophosphate (45.7 mg, 0.0000879 mol) in N,N-dimethylformamide (0.5 mL, 0.006 mol). The reaction mixture was stirred at room temperature for 2 hours. The crude product was purified by prep-LCMS. LC/MS: 402.1 (M+H+).
