Reaction Steps

A solution of N-(5-chloropyridin-2-yl)-2-hydroxy-benzamide (200 mg, 0.806 mmol), 1-tert-butoxycarbonyl-piperidine-4-methanol (191 mg, 0.887 mmol), and triphenylphosphine (232 mg, 0.887 mmol) in THF was treated dropwise with a THF solution of diethyl diazodicarboxylate (DEAD) (0.14 mL, 0.887 mmol in 1 mL of THF). After 16 h, the mixture was treated with an additional equivalent of triphenylphosphine and DEAD. After 2 h, the mixture was concentrated, diluted with methylene chloride, and filtered. The solid collected was the desired product (128 mg, 36%). The filtrate was purified by column chromatography (SiO2; 4:1 hexanes:EtOAc) providing an additional 142 mg (40%) of the title compound.
