実験手順

A solution of methyl 2-(1-benzyl-4-(4-chlorophenyl)-6-methyl-7-oxo-6,7-dihydro-1H-pyrrolo[2,3-c]pyridin-5-yl)-2-(tert-butoxy)acetate (30 mg, 0.061 mmol) in Methanol (0.500 mL), Tetrahydrofuran (THF) (0.500 mL) and Water (0.500 mL) was treated with NaOH (54.7 mg, 1.368 mmol) and heated to 70° C. for 3 hours. The mixture was cooled to 0° C., treated with HCl (1M) until pH<2 and extracted with Ethyl acetate. The combined extracts were washed with brine, dried over Na2SO4, filtered and concentrated. The residue was purified by reverse phase chromatography (10-90% MeCN/H2O-0.1% TFA, 12 min) to afford 2-(1-benzyl-4-(4-chlorophenyl)-6-methyl-7-oxo-6,7-dihydro-1H-pyrrolo[2,3-c]pyridin-5-yl)-2-(tert-butoxy)acetic acid (21.5 mg, 0.044 mmol, 73% yield) as white solid. 1H NMR (400 MHz, DMSO-d6) ppm 13.33 (s, 1H) 7.58-7.69 (m, 2H) 7.42-7.54 (m, 3H) 7.23-7.38 (m, 4H) 5.89-5.95 (m, 1H) 5.74-5.81 (m, 1H) 5.07-5.15 (m, 1H) 3.50-3.59 (m, 3H) 0.88 (s, 9H); LCMS (m/z) ES+=479 (M+1).
