Procedure
Morpholine (2 μL, 0.024 mmol, 1.0 eq) is added at room temperature to a stirred solution of 1-(6-methoxy-3,4-dihydro-2H-1-oxa-9-aza-phenanthren-3-ylmethyl)-4-[(3-oxo-3,4-dihydro-2H-benzo[1,4]thiazine-6-carbonyl)-amino]-pyrrolidine-2-carboxylic acid (14 mg, 0.024 mmol, 1.0 eq) in N,N-dimethylformamide (2 mL), followed by 1-hydroxybenzotriazole (4 mg, 0.027 mmol, 1.1 eq), N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (5 mg, 0.028 mmol, 1.15 eq) and N,N-diisopropylethylamine (13 μL, 0.073 mmol, 3.0 eq). After 15 hours stirring at room temperature, solvent is evaporated and the residue is extracted with dichloromethane (3×5 mL) and water (5 mL). The combined organic layers are dried over sodium sulfate, filtered and concentrated to give a crude product that is purified by preparative HPLC to afford 3-oxo-3,4-dihydro-2H-benzo[1,4]thiazine-6-carboxylic acid [1-(6-methoxy-3,4-dihydro-2H-1-oxa-9-aza-phenanthren-3-ylmethyl)-5-(morpholine-4-carbonyl)-pyrrolidin-3-yl]-amide as a white lyophilized powder (12 mg, 76% yield).
