Procedure

(2-Fluoro-biphenyl-4-yl)-acetic acid (0.12 gm, 0.5 mmole), 3-fluorobenzylamine (0.0.8 ml, 0.6 mmole), PyBOP (0.34 gm, 0.6 mmole), and DIEA (0.22 ml, 1.3 mmole) was dissolved in DMF stirred overnight, the reaction mixture was then poured into water, solid was collected by filtration, re-crystallized using water-methanol. (0.140 gm, 83%); H1-NMR INOVA-500 (DMSO d6) δ 3.580(s, 2H), 4.316(d, J=5.5 Hz, 2H), 7.037-7.110(m, 3H), 7.210-7.247(m, 2H), 7.343-7.372(m, 2H), 7.457-7.501(m, 3H), 7.544(d, J=8.0 Hz, 2H), 8.660(t, J=6.0 Hz, 1H). MS (m/z) 338.1 (M+H)+.
