Reaction Steps

To a solution of N-(1S, 2S)-[2-(3-cyanophenyl)-3-(4-hydroxyphenyl)-1-methylpropyl]amine hydrochloride (Reference Example 8, 0.17 g, 0.49 mmol), 2-methyl-2-(5-methyl-2-pyridyloxy)propionic acid (Reference Example 12, 96 mg, 0.49 mmol) and 1-ethyl-3-(3-dimethylaminopropyl)-carbodiimide hydrochloride (0.11 g, 0.59 mmol) in acetonitrile (2 mL) at 0° C. was added pyridine (91 uL, 1.1 mmol). The reaction was allowed to warm up to room temperature overnight, and was quenched with saturated with sodium bicarbonate (2 mL). The resulting mixture was partitioned between tert-butyl methyl ether (20 mL) and water (20 mL). The organic layer was separated, washed with 1 M hydrochloric acid, water and brine and concentrated to dryness. The residue was purified by flash column chromatography on silica gel eluting with 10 to 70% ethyl acetate in hexane to afford N-[2-(3-Cyano-phenyl)-3-(4-hydroxyphenyl)-1-methylpropyl]-2-(5-methyl-2-pyridyloxy)-2-methylpropanamide. 1H NMR (500 MHz, CD3OD): δ 7.85 (br d, 1H), 7.81 (d, 1H), 7.53-7.80 (m, 2H), 7.38 (t, 1H), 7.34 (br d, 1H), 7.32 (br s, 1H), 6.80 (d, 1H), 6.51 (ABq, 4H), 4.26 (m, 1H), 3.01 (dd, 1H), 2.81 (td, 1H), 2.54 (dd, 1H), 2.12 (s, 3H), 1.73 (s, 3H), 1.67 (s, 3H), 0.83 (d, 3H). LC-MS: m/e 444 (M+H)+ (3.3 min).
