Procedure
To a suspension of 5-(4-Fluorophenyl)-4-oxo-1,4-dihydropyridine-3-carboxylic acid 8d (J. Med. Chem. 2008, 51, 5330-5341) (8.0 g, 34.3 mmol) in anhydrous DMF (56 ml) were added HATU (15.65 g, 41.2 mmol) and i-Pr2NEt (18 ml, 104 mmol) at ice bath temperature under nitrogen. The mixture turned into a clear solution after being stirred for 5 min. To the solution was added 4-(4-Amino-2-Methyl-phenoxy)-7,8,10,11,13,14-hexahydro-6,9,12,15-tetraoxa-1,3-diaza-cyclododeca[b]naphthalene 7a (7.9 g, 32.5 mmol) slowly. The reaction mixture was stirred for 3 h at room temperature and was poured into aqueous 1N HCl solution. The solid that formed was filtered, washed with distilled water, and dried. The crude product was purified by silica gel chromatography, eluting with 1-5% of MeOH in CH2Cl2 to obtain 9a as a light-yellow solid (5.9 g, 40%), mp 188-190° C. HPLC purity 97%; 1HNMR (400 MHz, DMSO) δ 13.13 (s, 1H), 12.68 (br s, 1H), 8.62 (m, 2H), 7.97-8.12 (m, 2H), 8.04-7.99 (m, 2H), 7.78 (m, 1H), 7.69 (m, 2H), 7.42 (d, 2H), 7.21 (m, 2H), 4.35 (s, 4H), 3.87 (d, 4H), 3.62 (s, 4H). LC/MS Calcd for (M+H)′ 617.6. found 617.5.
