Reaction Steps

To a 25 ml flask was added (S)-2-amino-N-(1-ethyl-3-(pyridin-4-yl)-1H-pyrazol-5-yl)-3-phenylpropanamide 101.1.B (132 mg, 0.39 mmole), 3 ml of ethanol and 0.08 ml of triethylamine. The reaction mixture was cooled to 0° C., and then ethyl bromoacetate (48 μl, 0.43 mmole) was added to the mixture. The reaction was stirred at 50° C. for 1 hour and at room temperature overnight. After then, the solution was concentrated, and dissolved in ethyl acetate. The organic layer was washed with water and brine, and dried over anhydrous sodium sulfate. After concentration in vacuo, the residue was chromatographed on silica gel to give 101.1.C (45 mg, 27% yield) as colorless amorphous. 1H NMR (400 MHz, CDCl3) δ ppm 9.73 (s, 1H), 8.61 (d, J=5.9 Hz, 2H), 7.69 (d, J=6.3 Hz, 2H), 7.38-7.26 (m, 5H), 6.87 (s, 1H), 4.19-4.04 (m, 4H), 3.54 (dd, J=8.4, 4.5 Hz, 1H), 3.42 (d, J=17.6 Hz, 1H), 3.32 (d, J=17.6 Hz, 1H), 3.35 (dd, J=14.1, 4.5 Hz, 1H), 3.00 (dd, J=14.1, 8.2 Hz, 1H), 2.05 (brs, 1H), 1.43 (t, J=7.2 Hz, 3H), 1.24 (t, J=7.2 Hz, 3H).
