Reaction Steps

Intermediate 136 was coupled with 2-(3,5-difluoro-phenyl)-ethylamine following procedure F. The resulting product was deprotected following procedure G3. LC-MS showed the product had the expected M+H+ of 418 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 8.70 (s, 1H) 8.39 (d, 2H) 7.97 (d, 1H)) 7.74 (d, 2H) 7.00 (d, 2H) 6.86 (d, 1H) 4.57 (s, 2H) 4.06 (m, 1H) 3.88 (m, 1H) 3.72 (m, 1H) 3.57 (m, 1H) 3.42 (d, 2H) 3.10 (t, 2H) 2.92 (m, 2H) 2.38 (m, 2H) 1.38 (d, 3H).
