PROCEDURE

实验过程

A mixture of 2-phenoxyquinoline-8-carboxylic acid (119 mg, 0.449 mmol), 2-chloropyridine-3,4-diamine (97 mg, 0.673 mmol, Waterstone Technology, Carmel, Ind.), HATU (341 mg, 0.897 mmol), and DIPEA (235 μl, 1.346 mmol) in DMF (449 μl) was stirred at RT for 2 h. The mixture was diluted with EtOAc (100 ml), added to a separatory funnel, and washed with saturated aq. NaHCO3 (3×75 ml) before the organic layer was separated, dried over Na2SO4, and concentrated. Purification by silica chromatography (100% DCM to 5% MeOH/DCM) provided N-(3-amino-2-chloropyridin-4-yl)-2-phenoxyquinoline-8-carboxamide (or N-(4-amino-2-chloropyridin-3-yl)-2-phenoxyquinoline-8-carboxamide; regioisomer not determined; 178d, 49% yield). MS (ESI, pos. ion) m/z: 391.2 (M+1).
