Using General Procedure A: Reaction of bis-(3-methyl-pyridin-2-ylmethyl)-amine, 2-(4-Bromomethyl-thiophen-3-ylmethyl)-isoindole-1,3-dione, and DIPEA in CH3CN gave 2-(4-{[bis-(3-methyl-pyridin-2-ylmethyl)-amino]-methyl}-thiophen-3-ylmethyl)-isoindole-1,3-dione as a white foam. Deprotection with H2NNH2H2O using General Procedure E gave the free base as a pale yellow solid. Conversion to the HBr salt gave COMPOUND 396 as a beige solid. 1H NMR (D2O) δ 2.43 (s, 6H), 3.88 (s, 2H), 3.99 (s, 2H), 4.31 (s, 4H), 7.29 (d, 1H, J=3 Hz), 7.48 (d, 1H, J=3 Hz), 7.79 (dd, 2H, J=6.0, 7.8 Hz), 8.31 (d, 2H, J=7.8 Hz), 8.55 (d, 2H, J=6.0 Hz); 13C NMR (D2O) δ 17.39, 36.42, 53.37, 54.95, 126.10, 127.73, 128.48, 132.21, 134.97, 137.81, 139.23, 148.51, 150.64; ES-MS m/z 353 (M+H).
