Reaction Steps
Following General Procedure C: To a solution of [1-((R)-3-amino-1-methyl-propyl)-piperidin-4-yl]-[4-(2-methoxy-ethoxy)-phenyl]-(4-methyl-pyridin-3-ylmethyl)-amine (130 mg, 0.31 mmol) and 2,4-dimethyl-6-chloronicotinic acid (68 mg, 0.31 mmol) in DMF (4 mL) was added DIPEA (0.8 mL), HOBT (75 mg, 0.56 mmol) and EDCI (89 mg, 0.46 mmol) and the reaction stirred overnight. Purification of the crude product by column chromatography on silica gel (CH2Cl2/MeOH/NH4OH,) gave 42 mg (23%) of the title compound as a white solid: 1H NMR (CDCl3) δ 1.02 (d, 3H, J=6 Hz) 1.07-1.32 (m, 2H), 1.53-1.61 (m, 1H), 1.83-1.91 (m, 3H), 2.29 (s, 3H), 2.34 (s, 3H), 2.48 (s, 3H, 2.76-2.91 (m, 3H), 3.26-3.39 (m, 3H), 3.43 (s, 3H), 3.68-3.71 (m, 2H), 3.73-3.82 (m, 1H), 4.01-4.04 (m, 4H), 6.64 (d, 2H, J=9 Hz), 6.76 (d, 2H, J=9 Hz), 6.98 (s, 1H), 7.03 (d, 1H, J=6 Hz), 7.97 (br s, 1H), 8.26 (s, 1H), 8.29 (d, 1H, J=6 Hz). 13C NMR (CDCl3) δ 13.60, 19.19, 22.52, 29.68, 30.58, 31.80, 39.70, 44.36, 47.79, 59.57, 60.04, 68.06, 71.53, 115.72, 120.29, 122.88, 125.50, 148.34, 149.57. ES-MS m/z 594 (M+H). Anal. Calcd. for C33H44N5ClO3.0.2CH2Cl2: C, 65.24; H, 7.32; N, 11.46. Found: C, 64.88; H, 7.36; N, 11.54.
