실험 절차

10-(4-Cyclohex-1-en-1-yl-3-methyl-benzoyl)-10,11-dihydro-5H-pyrrolo[2,1-c][1,4]benzodiazepine-3-carboxylic acid (0.300 g, 0.703 mmol) of Example 5 Step E, D-serine methyl ester hydrochloride (0.131 g, 0.844 mmol), 1-hydroxy benzotriazole (0.104 g, 0.773 mmol) and 1-[3-dimethylamino)propyl]-3-ethylcarbodiimide hydrochloride (0.148 g, 0.773 mmol) were combined in amine-free N,N-dimethylformamide (2.8 mL), followed by the addition of N,N-diisopropylethylamine (0.307 mL, 1.76 mmol). The reaction was stirred at room temperature for 12 hours, then diluted with ethyl acetate and washed with water, 1 N hydrochloric acid, 1 N sodium hydroxide and brine. The combined aqueous washings were saturated with sodium chloride, and extracted with ethyl acetate. The organic phases were combined, dried over anhydrous magnesium sulfate, filtered and concentrated. The residue was purified by flash column chromatography on silica gel eluting with 10% methanol in chloroform, to afford 0.320 g of the title compound as a pale yellow solid.
