Procedure

Alternatively, 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 methanesulfonyl chloride (4.5 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 7 mg (51%) of N-[(1,3-benzodioxol-5-yl)methyl]-1-[2-(1H-imidazol-1-yl)pyrimidin-4-yl]-N-(methylsulfonyl)piperidine-2-ethanamine (the compound of formula (Iff)); 1H NMR (CDCl3) δ8.10 (s, 1), 7.78 (d, 1), 7.13 (s, 1), 6.82 (s, 1), 7.72 (s, 2), 6.30 (d, 1), 5.94 (s, 2), 4.23 (m, 3), 3.20 (m, 2), 2.80 (s, 3), 1.14 (m); MS: 485.7 (M+H)+.
