Reaction Steps

To a solution of N-(4-chlorophenyl)-2-[2-hydroxy-4-isopropylbenzylamino]pyridine-3-carboxamide (0.050 g, 0.13 mmol), triphenylphosphine (0.033 g, 0.13 mmol) and N-Boc-ethanolamine (0.018 mg, 0.11 mmol) in 0.3 mL tetrahydrofuran at −10° C. was added a solution of diethyl azodicarboxylate (0.02 mL, 0.13 mmol) in 0.3 mL tetrahydrofuran. The reaction was stirred at room temperature for 3 days. The solvent was removed in vacuo; and the crude material was purified by chromatography over silica, using an eluent gradient of 20-30% ethyl acetate in hexanes, to afford the named product (0.02 g, 30%).
