With sodium metabisulfite; triethylamine In N,N-dimethyl-formamide at 90℃; | 8 Example 8[5-(5-Fluoro-4-methyl-1H-benzoimidazol-2-yl)-4-methyl-pyrimidin-2-yl]-[3-(1-methyl-piperidin-4-yl)-propyl]-amine; To a 2 L Erlenmeyer flask were added 4-fluoro-3-methyl-benzene-1,2-diamine.HCl (46.32 g, 262.3 mmol), Na2S2O5 (64.82 g, 341.0 mmol), and 4-methyl-2-[3-(1-methyl-piperidin-4-yl)-propylamino]-pyrimidine-5-carbaldehyde (72.5 g, 262.3 mmol) in DMF (725 mL). To the resultant mixture was then added triethylamine (36.6 mL, 262.3 mmol), and the reaction was warmed on a hot plate with stirring to 90° C. and held at this temperature for 2 hours. The resultant mixture was then concentrated to near dryness and partitioned between dichloromethane (1 L) and 1 N NaOH (1 L). After separation of the layers, the aqueous layer was extracted a second time with dichloromethane (1 L). The combined organic layers were then washed with saturated aqueous NaHCO3 (1.6 L). The organics were then extracted with a 1 M mono/dibasic phosphate buffer (pH 5.62, 1.23 L). The aqueous layer was then basified with 50% NaOH (80 mL) to pH 10.8. The resultant heterogeneous layer was then extracted with dichloromethane (1.5 L and 500 mL), and the combined organics were concentrated to yield the title compound.The title compound was recrystallized from hot heptane/ethyl acetate (2:1, 1.15 L total volume) with initial hot filtration and final filter cake washing with heptane/ethyl acetate (3:1, 250 mL total volume) to yield the title compound as a crystalline solid.1H-NMR: (400 MHz, CD3OD) 6, 8.45 (s, 1H), 7.37 (dd, J=8.8, 4.4 Hz, 1H), 6.99 (dd, J=10.3, 8.8 1H), 3.42 (t, J=7.0, 2H), 2.89-2.82 (m, 2H), 2.54 (s, 3H), 2.49 (d, J=1.6 Hz, 3H), 2.24 (s, 3H), 2.03-1.94 (m, 2H), 1.77-1.70 (m, 2H), 1.69-1.61 (m, 2H), 1.38-1.18 (m, 5H).MS (electrospray): exact mass calculated for C22H29FN6, 396.2; m/z found, 397.2 [M+H]+ Elemental Analysis for C22H29FN6: Calculated: C, 66.64; H, 7.37; N, 21.19.
