Following the procedure as described in Example 14, making variations as required to replace oxazol-4-ylmethanamine with (1H-pyrazol-3-yl)methanamine to react with 2-(3-(4-fluorobenzyl)-2-oxoimidazolidin-1-yl)isonicotinic acid, N-((1H-pyrazol-3-yl)methyl)-2-(3-(4-fluorobenzyl)-2-oxoimidazolidin-1-yl)isonicotinamide was obtained as a colorless solid in 23% yield: mp 178-180° C.; 1H NMR (300 MHz, CDCl3) δ 8.60 (s, 1H), 8.33-8.24 (m, 2H), 7.45-7.37 (m, 2H), 7.32-7.17 (m, 3H), 7.04-6.94 (m, 2H), 6.27 (s, 1H), 4.70 (d, J=5.7 Hz, 2H), 4.43 (s, 2H), 4.03 (t, J=8.1 Hz, 2H), 3.37 (t, J=8.1 Hz, 2H); MS (ES+) m/z 394.9 (M+1).
