Procedure

3-fluorobenzylamine (0.14 ml, 1.1 mmole), PyBOP (0.57 gm, 1.1 mmole), and DIEA (0.36 ml, 2.2 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. (0.22 gm, 76%); H1-NMR INOVA-500 (DMSO d6) δ 3.550 (s, 2H), 4.303 (d, J=6.5 Hz, 2H), 7.027-7.097 (m, 3H), 7.197 (m, 1H), 7.350 (m, 1H), 7.389 (d, J=8.0 Hz, 2H), 7.477-7.518 (m, 3H), 7.657 (d, J=8.0 Hz, 2H), 8.652 (t, J=5.5 Hz, 1H). MS (m/z) 338.1 (M+H)+.
