실험 절차

This compound (365 mg, 94% yield) as a tan crystalline solid was prepared similarly to that described in Example 167a, using 8-bromoquinoline-2-carboxylic acid (Princeton BioMolecular Research, Monmouth Junction, N.J.; 320 mg, 1.27 mmol), oxalyl chloride (2.54 mmol), and pyrrolidine (0.10 mL, 1.27 mmol) as starting materials. 1H NMR (400 MHz, DMSO-d6) δ ppm 8.59 (1H, d, J=8.4 Hz), 8.23 (1H, dd, J=7.6, 1.2 Hz), 8.11 (1H, dd, J=8.2, 1.0 Hz), 8.01 (1H, d, J=8.6 Hz), 7.63 (1H, t, J=7.8 Hz), 3.98 (2H, t, J=6.5 Hz), 3.61 (2H, t, J=6.5 Hz), 1.95 (4H, m). m/z (ESI, +ve) 307/307 (M+H)+.
