Procedure

Carboxylic acid 213 (0.015 g, 0.029 mmol) was dissolved in 0.8 mL of dimethylformamide. To this was added BOC-piperazine (0.0116 g, 0.058 mmol), triethylamine (0.012 mL, 0.087 mmol), 1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (0.011 g, 0.058 mmol), 1-Hydroxybenzotriazole hydrate (0.0059 g, 0.0435 mmol) and stirred at room temperature. After 15 hours, starting material was consumed. Dilute with dichloromethane, washed with 1M HCl solution, saturated brine solution, dried (Na2SO4), concentrated to give crude product. Chromatographed (10 to 50% ethyl acetate/hexanes) to give 4-[9-benzhydryloxy-7-(4-fluoro-benzyl)-8-oxo-7,8-dihydro-6H-pyrrolo[3,4-g]quinoline-5-carbonyl]-piperazine-1-carboxylic acid tert-butyl ester 229 (0.009 g, 0.013 mmol, 45%.) 1H NMR (CDCl3) 9.075 (s, 1H), 8.15 (s, 1H), 8.03 (d, 1H), 7.74 (dd, 4H), 7.53 (dd, 1H), 7.27 (m, 8H), 7.04 (dd, 2H), 4.91 (d, J=17 Hz, 1H), 4.69 (d, J=17 Hz, 1H), 4.41 (d, J=17 Hz, 1H), 4.055 (d, J=17 Hz, 1H), 3.55-2.96 (br m, 8H), 1.44 (s, 9H.) MS: 687 (M+1).
