実験手順

A solution of methyl 2-(1-{2-[(methylsulfonyl)oxy]ethyl}-1H-imidazol-4-yl)pyridine-4-carboxylate (150 mg, 0.46 mmol) and N-methylbenzylamine (558 mg, 4.6 mmol) in toluene (8 mL) was heated at 110° C. in a sealed tube for 7 hrs. The solution was concentrated to an oily residue and chromatographed on silica gel (EtOAc/Hex, 1:1) to give the title compound (118 mg) as an amber oil: 1HNMR (400 MHz, CDCl3): δ 2.28 (3H, s), 2.78 (2H, t, J=4.2 Hz), 3.61 (2H, s), 3.94 (3H, s), 4.03 (2H, t, J=4.2 Hz), 7.19-7.27 (5H, m), 7.58 (1H, s), 7.61 (1H, s), 7.64 (1H, m), 8.47 (1H, s), 8.63 (1H, m). [M+H] Calc'd for C20H22N4O2, 351. Found, 351.
