Reaction Steps

A suspension comprising 2-amino-pyridine-3-carbaldehyde (5 g, 40.9 mmol) and deoxybenzoin (8.03 g, 40.9 mmol) in piperidine (4.46 ml, 45.0 mmol) was heated at 120° C. overnight. The resulting solution was partitioned between DCM (200 ml) and water (200 ml). The organic layer was separated and washed with water (2×150 ml), brine, dried over MgSO4, filtered and concentrated in vacuo. The crude product was purified by chromatography on silica eluting with 0-50% EtOAc in iso-hexane to afford the title product as a yellow solid;
