Vorschrift

To a solution of 5-(5,6,7,8-tetrahydro-pyrido[3,4-d]pyrimidin-4-yloxy)-indole-1-carboxylic acid (3-trifluoromethyl-phenyl)-amide, Example 31-C, (120 mg, 0.26 mmol), HATU (198 mg, 0.52 mmol), DIEA (0.2 mL, 1.30 mmol) and DMF (5 mL) is added 3-diethylamino-propionic acid hydrochloride (47 mg, 0.26 mmol). After stirring at rt for 2 h the contents of the flask are partitioned between DCM and 10% aqueous LiCl. Organic layer is removed, dried over anhydrous Na2SO4 and concentrated in vacuo. The residue is then separated via semi-prep HPLC (C18; 10-100% I/H2O with 0.1% NH4OH) to give the title compound.
