反応手順

A solution of diethyl azodicarboxylate (1.73 ml) in dried tetrahydrofuran (10 ml) was added dropwise to a stirred mixture of triphenylphosphine (3.15 g), 4-cyanophenol (1.31 g) and 4-(3-hydroxy-1-pyrrolidinyl)pyridine (1.64 g) in dried tetrahydrofuran (45 ml), under an atmosphere of argon, at 5-7° C. The resulting solution was stirred at ambient temperature for 16 hours. The solid, which had separated, was filtered off and washed with diethyl ether to give 4-[3-(4-cyanophenoxy)-1-pyrrolidinyl]pyridine (823 mg) as an off-white solid, mp 182-185° C.
