Procedure

To THF (3 mL) was added N-[(1,3-benzodioxol-5-yl)methyl]-1-[2-(1H-imidazol-1-yl)pyrimidin-4-yl]piperidine-2-ethanamine (8 mg, 0.03 mmol), Hünig's base (8 mg, 0.06 mmol), and acetic anhydride (4 mg, 0.04 mmol). After stirring for 16 hours, the solvent was removed in vacuo and the residue was chromatographed (CH2Cl2/MeOH. 19/1) to give 8 mg (60%) of N-acetyl-N-[(1,3-benzodioxol-5-yl)methyl]-1-[2-(1H-imidazol-1-yl)pyrimidin-4-yl]piperidine-2-ethanamine (the compound of formula (Igg)): 1H NMR (CDCl3) δ 8.48 (s, 1), 8.08 (d, 1), 7.76 (s, 1), 7.09 (s, 1), 6.66 (m, 3), 6.33 (m, 1), 5.94 (s, 1), 5.91 (s, 1), 4.43 (m,3), 3.40 (m, 2), 2.11 (d, 3), 1.14 (m); MS: 450.0 (M+H)+.
