Reaction Steps

Combine 4-[5-(Piperidine-1-carbonyl)-pyridin-2-yloxy]-benzaldehyde (72.0 mg, 0.23 mmol), MeOH (2.3 mL), Trimethylorthoformate (1.6 mL), and Phenethylamine (26 uL, 0.21 mmol). After the reaction stirs for 72 hours at room temperature under a Nitrogen atmosphere, add NaBH4 (10.5 mg, 0.28 mmol). After 5 hours, concentrate the reaction under reduced pressure and add the mixture to a 2 g SCX column. Wash with MeOH and then 1N NH3 MeOH to afford 72.2 mg (75% yield) of the title compound: 1H NMR (500 MHz, CDCl3); 1.5-1.8 (6H, m), 2.8-3.0 (4H, m), 3.3-3.8 (4H, m), 3.85 (2H, s), 6.8 (1H, d), 7.1-7.4 (9H, m), 8.0 (1H, d), 8.2 (1H, s); MS m/z 416 (M+1).
