Reaction Steps

tert-Butyl 4-[4-(2-hydroxyethyl)benzyl]piperazine-1-carboxylate (1.44 g), 2-hydroxy-5-methylpyridine (0.737 g), tri-n-butylphosphine (1.76 mL), 1,1′-(azodicarbonyl)-dipiperidine (1.70 g), and THF (16.5 mL) were mixed in a 20 mL process vial. The vial was sealed, and the reaction mixture was heated with microwaves to 55 ° C. for 10 minutes. The reaction mixture was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (n-hexane/AcOEt =10/1 to 3/10) to give tert-butyl 4-(4-{2-[(5-methylpyridin-2-yl)oxy]ethyl}benzyl)piperazine-1-carboxylate as a pale yellow amorphous (1.01 g).
