実験手順

General Procedure M. To a solution of 5,6-diphenylpyridine-2-carbaldehyde (Compound 54, 95 mg, 0.37 mmol) and (3-amino-propyl)-phosphonic acid (51 mg, 0.37 mmol) in MeOH (3 ml) was added Bu4NOH (0.4 ml, 0.37 mmol, 1M in MeOH) under argon. The mixture was stirred at 50° C. for 30 min. before adding NaCNBH3 (23 mg, 0.37 mmol) to the mixture. The solution was stirred at 50° C. for 3 hours, and then it was concentrated in vacuo. The resulting crude solid was purified MPLC column chromatography (silica gel, 0-100% MeOH in ethyl acetate) to obtain the title compound as a white solid.
