Following the procedure as described in Example 15, making variations as required to replace methyl 2-(3-(4-fluorobenzyl)-2-oxoimidazolidin-1-yl)isonicotinate with methyl 2-(2-oxo-3-(pyridin-4-ylmethyl)imidazolidin-1-yl)isonicotinate to react with benzylamine, N-benzyl-2-(2-oxo-3-(pyridin-4-ylmethyl)imidazolidin-1-yl)isonicotinamide was obtained as a colorless solid in 37% yield: mp 154-156° C.; 1H NMR (300 MHz, DMSO-d6) δ 9.25 (t, J=5.9 Hz, 1H), 8.60 (s, 1H), 8.52-8.50 (m, 2H), 8.38 (d, J=5.4 Hz, 1H), 7.37-7.18 (m, 8H), 4.45-4.43 (m, 4H), 3.99 (t, J=7.9 Hz, 2H), 3.42 (t, J=7.9 Hz, 2H); MS (ES+) m/z 387.8 (M+1).
