Procedure
A solution of 2-[4-(2-chloro-phenoxy)-2-oxo-2,5-dihydro-pyrrol-1-yl]-3-phenyl-propionic acid [1-((R)-2,2-dimethyl-[1,3]dioxolan-4-yl-methyl)-1H-pyrazol-3-yl]-amide (0.010 g, 0.017 mmol) in tetrahydrofuran (1 mL) was treated with 2N aqueous hydrochloric acid solution (1 mL). The reaction mixture was stirred at 25° C. for 3 h. The reaction mixture was diluted with ethyl acetate, washed with water, saturated sodium bicarbonate solution, a saturated sodium chloride solution and dried over magnesium sulfate. The organic layer was concentrated to afford, 2-[4-(2-chloro-phenoxy)-2-oxo-2,5-dihydro-pyrrol-1-yl]-3-phenyl-N-[1-((R)-2,3-dihydroxy-propyl)-1H-pyrazol-3-yl]-propionamide (0.007 g, 82%) as an off-white powder: HR-ES-MS m/z calculated for C23H27ClN4O6 [M+H]+ 497.1587, observed 497.1586; 1H NMR (300 MHz, CDCl3) δ ppm 1.75 (br. s., 2H), 3.17 (dd, J=14.0, 8.8 Hz, 1H), 3.39 (dd, J=14.0, 6.9 Hz, 1H), 3.44-3.55 (m, 2H), 3.56-3.65 (m, 1H), 3.95-4.10 (m, 2H), 4.16 (d, J=18.1 Hz, 1H), 4.30 (d, J=18.1 Hz, 1H), 4.77 (s, 1H), 5.02 (t, J=7.8 Hz, 1H), 6.65 (d, J=1.8 Hz, 1H), 7.17 (dd, J=8.2, 1.8 Hz, 1H), 7.19-7.26 (m, 6H), 7.28-7.35 (m, 2H), 7.46 (dd, J=7.8, 1.5 Hz, 1H), 9.65 (s, 1H).
