Reaction Steps

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. MS (ESI) m/z 581.2 (M+1); 1H NMR (400 MHz, MeOD) δ ppm 8.40-8.48 (m, 1 H), 8.33 (d, J=8.8 Hz, 1 H), 8.06 (s, 1 H), 7.94 (d, J=3.5 Hz, 1 H), 7.89 (d, J=8.6 Hz, 1 H), 7.57 (t, J=8.1 Hz, 1 H), 7.36-7.47 (m, 2 H), 7.10 (dd, J=9.0, 2.1 Hz, 1 H), 6.74 (d, J=3.8 Hz, 1 H), 4.71-4.79 (m, 2 H), 3.85-4.05 (m, 2 H), 3.20 (d, J=5.8 Hz, 2 H), 2.84-3.08 (m, 8 H), 1.23 (q, J=7.1 Hz, 6 H).
