Using the general N-alkylation procedure: To a stirred solution of N-[6-(bromomethyl)-2-pyridyl]pivalamide (prepared as described by Harata, M.; Hasegawa, K.; Jitsukawa, K.; Masuda, H.; Einaga, H. Bull. Chem. Soc. Jpn 1998, 71, 1031-1038) (0.129 g, 0.45 mmol) in dry CH3CN (10 mL) was added (1-tert-butoxycarbonyl-1H-benzimidazol-2-ylmethyl)-(5,6,7,8-tetrahydro-quinolin-8-yl)-amine (0.176 g, 0.47 mmol), N,N-diisopropylethylamine (0.20 mL, 1.15 mmol) and potassium iodide (12 mg, 0.048 mmol). The mixture was stirred under an argon atmosphere at 60° C. for 3.75 h. Purification of the crude material by column chromatography on silica gel (CH2Cl2/MeOH, 98:2 followed by 96:4) gave the alkylated product (0.148 g, 54%) as a brown oil.
