Procedure

3-Iodopyridine (525 mg, 2.58 mmol), D-valine (250 mg, 2.13 mmol), copper(I) iodide (40.6 mg, 0.213 mmol), dimethylaminoethanol (400 mg, 4.49 mmol), potassium phosphate tribasic (1359 mg, 6.40 mmol), and water (2 mL) was stirred at 80° C. overnight. The reaction was washed with EtOAc, then the aqueous portion was concentrated. The residue was slurried with MeOH and the MeOH portion was concentrated. The product was isolated using preparative reverse phase HPLC (MeOH/water/TFA) and used in next step without further purification.
