実験手順
To a vial containing 6-trifluoromethoxy-2H-chromene-3-carboxylic acid (42 mg, 0.16 mmol) was added a solution containing N,N,N′,N′-tetramethyl-O-(7-azabenzotriazol-1-yl)uronium hexafluorophosphate (67.5 mg, 0.18 mmol), DIPEA (2.4 eq), and 4-dimethylaminopyridine (1.97 mg, 0.016 mmol) in anhydrous MeCN (3 mL). After stirring for 5 minutes, a solution of quinolin-4-yl-methylamine dihydrochloride (41 mg, 0.18 mmol) and DIPEA (2.4 eq) in anhydrous MeCN (2 mL) was added. The reaction was stirred overnight at room temperature. The reaction mixture was poured into saturated NaHCO3 solution (50 mL) and extracted with EtOAc (3×50 mL). The combined organics were washed with brine (3×50 mL), dried (MgSO4), filtered and concentrated. Flash chromatography (0 to 3% MeOH in DCM over 40 minutes) gave the product (6.3 mg) as a solid. m/z=401.4 (M+1), r.t.=2.76 mins. 1H NMR (400 MHz; DMSO-d6) δ 9.00 (1H, t), 8.86 (1H, d), 8.21 (1H, d), 8.06 (1H, d), 7.79 (1H, t), 7.67 (1H, t), 7.43 (1H, d), 7.37 (1H, s), 7.32 (1H, s), 7.25 (1H, d), 6.97 (1H, d), 5.03 (2H, s), 4.90 (2H, d).
