Procedure

A mixture of 4-[(1S)-1-({[5-chloro-2-(4-fluorophenoxy)pyridin-3-yl]carbonyl}amino)ethyl]benzoic acid (step 5 of Example 44, 250 mg, 0.60 mmol), methanesulfonamide (60 mg, 0.63 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (139 mg, 0.73 mmol) and dimethylaminopyridiene (78 mg, 0.63 mmol) in dichloromethane (5 mL) was stirred at room temperature overnight. The reaction mixture was diluted with ethyl acetate. The solution was washed with 1M hydrochloric acid, water, and brine, dried over sodium sulfate, and evaporated. The residue was purified by flush column chromatography on silica gel eluting with dichloromethane/methanol (40/1) to afford 292 mg (98%) of the title compound: 1H-NMR (CDCl3) δ 8.52 (1H, d, J=2.8 Hz), 8.14 (1H, d, J=2.8 Hz), 8.16–8.02 (1H, m), 7.81 (2H, d, J=8.3 Hz), 7.46 (2H, d, J=8.3 Hz), 7.23–7.10 (4H, m), 5.44–5.28 (1H, m), 3.41 (3H, s), 1.59 (3H, d, J=7.0 Hz); MS (ESI) m/z 492 (M+H)+, 490 (M−H)−.
