Reaction Steps

A mixture of HCl salt of 3-amino-2-(2-fluoro-phenyl)-propionic acid (82 mg), 4-hydroxy-7-phenoxy-isoquinoline-3-carboxylic acid methyl ester (40 mg) and DBU (0.112 mL) in DMA (1 mL) was heated in an oil bath (150° C.) for 1 h. The reaction mixture was then partitioned between EtOAc and diluted HCl solution, EtOAc phase was separated and washed with water, diluted NaCl solution and dried over anhydrous sodium sulfate solution, filtered, concentrated and silica gel column purified to give desired product (40 mg). LC-MS ESI+: 472 (M+1)+.
