Procedure

2-fluoro-5-((4-oxo-3,4-dihydrophthalazin-1-yl)methyl)benzoic acid (1) (0.20 g, 0.67 mmol) and HBTU (0.381 g, 1.01 mmol) were added to DMA (4 mL), to this was added N-ethyl-N-isopropylpropan-2-amine (0.179 mL, 1.01 mmol) and then 2-(piperidin-4-yloxy)-1-(pyrrolidin-1-yl)ethanone (106) (0.142 g, 0.67 mmol). The reaction was stirred for 2 hours before being evaporated to dryness and purified by preparative HPLC (Waters XBridge Prep C18 OBD column, 5μ silica, 21 mm diameter, 100 mm length), using decreasingly polar mixtures of water (containing 1% NH+) and MeCN as eluents. Fractions containing the desired compound were evaporated to dryness to the desired compound as a white solid (0.168 g, 50.9%); 1H NMR (400.132 MHz, CDCl3) δ 1.90-1.56 (m, 6H), 2.01-1.93 (m, 2H), 3.16-3.07 (m, 1H), 3.57-3.42 (m, 6H), 3.72 (septet, J=3.6 Hz, 1H), 4.06-4.00 (m, 1H), 4.12 (q, J=11.9 Hz, 2H), 4.26 (s, 2H), 7.02 (t, J=8.8 Hz, 1H), 7.32-7.25 (m, 2H), 7.79-7.70 (m, 3H), 8.47-8.44 (m, 1H), 10.01-9.97 (m, 1H); m/z (LC-MS, ESI+), RT=1.66 (M+H 493).
