実験手順
In a 2-5 mL Emrys™ process vial, a mixture of the 1-formyl-4-oxo-4H-quinolizine-3-carboxylic acid (76 mg, 0.35 mmol), 6-chloro-1,2,3,4-tetrahydroisoquinoline (82 mg, 0.49 mmol), glacial acetic acid (0.12 mL, 2.1 mmol) and 1.8 mL of dichloroethane was stirred vigorously. To the stirring mixture was added resin-bound MP-cyanoborohydride (343 mg, 0.70 mmol). The mixture was heated via Emrys Optimizer™ microwave to 120° C. for 30 minutes. Filtration and solvent removal provided material, which was subjected to preparative reverse phase HPLC. Collection of product containing fractions and removal of solvent yielded the title compound that gave a proton NMR spectrum consistent with theory and a high resolution mass spectrum (ES+) m/z of 369.1011 calculated for M+H+ [C20H17Cl1N2O3: 369.1001]: 1H NMR (500 MHz, CD3OD) δ 9.59 (d, J=7.1 Hz, 1H), 8.74 (s, 1H), 8.40 (d, J=8.8 Hz, 1H), 8.18 (t, J=73 Hz, 1H), 7.73 (t, J=6.6 Hz, 1H), 7.32 (s, 1H), 7.27 (d, J=8.3 Hz, 1H), 7.14 (d, J=8.6 Hz, 1H), 4.87 (s, 2H), 4.47 (s, 2H), 3.69 (bs, 2H), 3.20 (t, J=6.0 Hz, 2H).
