PROCEDURE
实验过程
To a solution of 10-(1-benzyl-piperidin-4-yl)-6-methoxy-10H-phenoxazine-3-carboxylic acid, 3d (240 mg, 0.56 mmol) in DMF was added HATU (424 mg, 1.11 mmol), N,N-diisopropyl-N-ethylamine (115 mg, 1.12 mmol), and N,N-diethylamine (82 mg, 1.12 mmol). The mixture was allowed to stir overnight at rt. Water (5 mL) was added, and the solution was extracted with EtOAc. The organic layer was separated, dried, and evaporated. The residue was purified via reverse phase HPLC (eluent: CH3CN in water containing 0.1% TFA) to yield 93.3 mg (28%) of 10-(1-benzyl-piperidin-4-yl)-6-methoxy-10H-phenoxazine-3-carboxylic acid diethylamide, 4d and 91.4 mg (29%) of 10-(1-benzyl-piperidin-4-yl)-6-methoxy-10H-phenoxazine-3-carboxylic acid dimethylamide, 5d, both as TFA salts (presence of 5d is presumably due to N,N-dimethylamine present in DMF). 4d: MS m/z (MH+) 486.0; 5d: MS m/z (MH+) 458.8.
