Versuchsvorschrift

To a solution of DMSO (3 mL) of (4-benzyloxy-phenyl)-acetic acid hydrazide (130 mg) described in Manufacturing Example 8-1 were added triethylamine (0.21 mL), 2-aminonicotinic acid (70 mg), and BOP reagent (benzotriazol-1-yloxytris(dimethylamino)phosphonium hexafluorophosphate) (250 mg), which was stirred for 1 hour at the same temperature. Water was added to the reaction solution, and the solids thus precipitated were filtered off to obtain the titled compound (170 mg).
