Reaction Steps

In a 2-5 mL Emrys™ process vial, a mixture of the 1-formyl-4-oxo-4H-quinolizine-3-carboxylic acid (35 mg, 0.16 mmol), 4-(3,5-difluorophenyl)piperidine (45.4 mg, 0.23 mmol), glacial acetic acid (0.055 mL, 0.97 mmol) and 0.80 mL of dichloroethane was stirred vigorously. To the stirring mixture was added resin-bound MP-cyanoborohydride (20.3 mg, 0.32 mmol). The mixture was heated via Emrys Optimizer™ microwave to 120° C. for 30 minutes. The reaction was filtered, providing material, which was purified by reverse phase HPLC to yield the title compound that gave a high resolution mass spectrum (ES+) m/z of 399.1512 calculated for M+H+ [C22H20F2N2O3: 399.1515].
