Reaction Steps

[3-({5-[5-Fluoro-2-oxo-1,2-dihydro-indol-(3Z)-ylidenemethyl]-2,4-dimethyl-1H-pyrrole-3-carbonyl}-amino)-propyl]-carbamic acid tert-butyl ester was suspended in methanol. 2 ml of HCl (4N) in dioxane was added and the reaction stirred at room temperature overnight. The solvent was removed to yield the desired compound (0.098 g, 91%). 1H NMR (400 MHz, DMSO-d6) δ 13.8 (s, 1H); 11.00 (s, 1H); 7.90-7.70 (m, 5H); 6.9 (m, 2H); 3.30 (q, 2H); 2.80 (q, 2H); 2.50 (dd, 6H) 1.80 (m, 2H). LCMS: inconclusive due to fluorescence.
