To 2-[(3-aminopropyl)[2-(1H-imidazol-1-yl)-6-methyl-4-pyrimidinyl]amino]-N-[2-(1,3-benzodioxol-5-yl)ethyl]acetamide (50 mg, 0.11 mmol) (a compound of formula (Yc6)) in methanol (2 mL) was added benzaldehyde (0.2 M in methanol, 68 μL, 0.14 mmol). After stirring for 15 minutes, borane-pyridine complex (0.2 M in methanol, 0.14 mmol) was added. After 2 hours, the solution was evaporated. The residue was partitioned into water and ethyl acetate. The aqueous layer was extracted twice with ethyl acetate. The combined ethyl acetate fractions were washed with brine, dried over sodium sulfate and concentrated. The residue was purified by chromatography on silica gel (2:1 ethyl acetate/hexanes) to provide 2-[[3-(phenylmethylamino)propyl][2-(1H-imidazol-1-yl)-6-methyl-4-pyrimidinyl]amino]-N-[2-(1,3-benzodioxol-5-yl)ethyl]acetamide, a compound of formula (Yc8); as a white solid; NMR (CDCl3) 8.65 (s, 1), 7.7 (s, 1), 7.2 (br, 5), 7.1 (s, 1), 6.6 (d, 1), 6.55 (s, 1), 6.5 (d, 1), 6.1 (br, 2), 5.9 (s, 2), 3.95 (br, 2), 3.5 (br, 6), 2.7 (m, 3), 2.35 (s, 6) ppm.
