A mixture of (R)-2-(3-(2-ethoxyphenoxy)piperidin-1-yl)pyrimidine-5-carboxylic acid (2.00 g, 5.82 mmol), (3-iodophenyl)methanamine (1.00 mL, 7.20 mmol), N-methyl morpholine (2.00 mL, 18 mmol), EDCl (1.2 g, 5.9 mmol), and HOBT (455 mg, 2.91 mmol) in THF (30 mL) was stirred at room temperature overnight. The reaction was diluted with EtOAc (50 mL). The organic layer was washed with saturated aqueous solution of NH4Cl (50 mL), saturated aqueous solution of NaHCO3 (50 mL), and brine (50 mL), dried over Na2SO4 and concentrated to dryness. The residue was purified by flash column chromatography (0-50% EtOAc in Heptanes) to afford (R)-2-(3-(2-ethoxyphenoxy)piperidin-1-yl)-N-(3-iodobenzyl)pyrimidine-5-carboxamide (2.39 g, 74%) as a solid. 1H NMR (400 MHz, CDCl3) δ 8.69 (s, 2H), 7.69 (m, 1H), 7.64 (m, 1H), 7.32 (m, 1H), 7.10 (t, 1H), 6.98 (m, 2H), 6.88 (m, 2H), 6.13 (t, 1H), 4.58 (d, 2H), 4.48 (dd, 1H), 4.25 (m, 1H), 4.18 (m, 1H), 4.01 (m, 2H), 3.77 (dd, 1H), 3.64 (m, 1H), 2.13 (m, 1H), 1.97 (m, 2H), 1.59 (m, 1H), 1.39 (t, 3H). MS (ES+) 559.2 (M+H).
