Procedure

To a mixture of N-(4-(2-aminoethoxy)-3-(1-methyl-1H-pyrazol-5-yl)phenyl)-3-methoxybenzamide (0.020 g, 0.15 mmol) and triethylamine (0.038 mL, 0.27 mmol) in dichloromethane was added hexanoyl chloride (50 mg, 0.14 mmol), dropwise at room temperature. The mixture was stirred at room temperature overnight. The reaction was quenched with water, extracted with dichloromethane (3×20 mL) and dried over anhydrous MgSO4. The crude product was purified by flash column chromatography. (EtOAc/Hexane=50-90%). N-[4-(2-Hexanoylamino-ethoxy)-3-(2-methyl-2H-pyrazol-3-yl)-phenyl]-3-methoxy-benzamide was obtained as white solid in 43% yield. LCMS m/z (%)=465 (M+H, 100). 1H NMR (400 MHz, CDCl3) δ ppm 0.9 (t, J=7.1 Hz, 3 H), 1.3 (m, 4 H), 1.6 (m, 2 H), 2.1 (m, 2 H), 3.5 (q, J=5.4 Hz, 2 H), 3.8 (s, 3 H), 3.9 (s, 3 H), 4.0 (t, J=5.1 Hz, 2 H), 5.5 (m, 1 H), 6.3 (d, J=2.0 Hz, 1 H), 7.0 (d, J=9.1 Hz, 1 H), 7.1 (m, 1 H), 7.4 (m, 2 H), 7.4 (d, J=2.0 Hz, 1 H), 7.6 (d, J=2.0 Hz, 1 H), 7.6 (d, J=3.0 Hz, 1 H), 7.7 (dd, J=8.8, 2.8 Hz, 1 H), 7.8 (s, 1 H).
