Procedure

To 2-[(2-cyanoethyl)[2-(1H-imidazol-1-yl)-6-methyl-4-pyrimidinyl]amino]-N-[2-(1,3-benzodioxol-5-yl)ethyl]acetamide (2.5 g, 5.8 mmol) (a compound of formula (Yc3)) in MeOH (50 mL) was bubbled ammonia. Raney nickel (1.0 g of a 50% slurry) was added and the reaction was placed on a Parr hydrogenator at 50 psi. After shaking for 16 hours, the pressure was released and the reaction mixture was suction filtered through Celite. The solvent was removed in vacuo and the residue was chromatographed on silica gel (9:1 CH3CN/NH4OH) to afford 2-[(3-aminopropyl)[2-(1H-imidazol-1-yl)-6-methyl)-4-pyrimidinyl]amino]-N-[2-(1,3-benzodioxol-5-yl)ethyl]acetamide, a compound of formula (Yc6); as a white solid; NMR (DMSO-d6, 90° C.) 8.4 (s, 1), 7.8 (s, 1), 7.0 (s, 1), 6.75 (d, 1), 6.7 (s, 1), 6.6 (d, 1), 5.9 (s, 2), 4.1 (s, 2), 3.6 (br, 2), 3.3 (m, 2), 2.75 (t, 2), 2.6 (t, 2), 2.3 (s, 3), 1.8 (m, 2) ppm.
