Procedure

Lithium hydroxide monohydrate (5.5 mg, 0.13 mmol, 1.5 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 methyl ester (70 mg, 0.09 mmol, 1.0 eq) in tetrahydrofuran (2 mL) and water (1 mL). After 1 hour stirring at room temperature, the reaction mixture is concentrated and purified by preparative HPLC to afford 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 as a white lyophilized powder (14 mg, 28% yield).
