Intermediate 142 was coupled with 2-(3,5-difluoro-phenyl)-ethylamine following procedure F. The resulting product was deprotected following procedure G2. LC-MS showed the product had the expected M+H+ of 438. 1H NMR (Varian 300 MHz, CD3OD, shifts relative to the solvent peak at 3.3 ppm) δ 8.32 (s, 1H) 8.12 (d, 1H)) 7.98 (d, 1H) 7.47 (m, 2H) 7.12 (d, 1H) 6.90 (d, 2H) 6.75 (d, 1H) 3.75 (t, 2H) 3.60 (m, 4H) 3.47 (t, 2H) 2.98 (t, 2H) 2.90 (t, 2H) 1.04 (d, 6H).
