実験手順

To a solution of 2-methoxymethyl-4-piperazin-1-yl-pyrimidine (prepared according to the method of Preparation One, 2.08 g, 10 mmol) and triethylamine (1.01 g, 10 mmol) in tetrahydrofuran (20 mL) was added N-pyrrolidinesulfonyl chloride (1.69 g, 10 mmol) at 0° C. and stirred for 3 h at ambient temperature. The mixture was diluted with ethyl acetate and washed twice with water. The organic layer was separated, dried over magnesium sulfate, filtered, and the filtrate was concentrated to an oil which was purified by flash chromatography (95:5 dichloromethane:methanol) to give the title compound of Example 121, Step A as a clear oil, 3.24 g (93%). 1H NMR (COCl3, 300 MHz) δ 1.81-1.85 (m, 4H), 3.12-3.18 (m, 8H), 3.59 (s, 3H), 3.81 (m, 4H), 4.43 (s, 2H), 6.71 (d, 1H), 8.18 (d, 1H); MS (TS) 342 (MH+).
