실험 절차
In a microwave reaction vessel, slurry 4,6-dichloropyrimidine (540 mg, 3.6 mmol), cyclopropylmethylamine (2800 L, 3.24 mmol), and diisopropylethylamine (1.25 mL, 7.2 mmol) in iso-propanol (3 mL). Irradiate in microwave (300 watts) at 140° C. for 40 min. Cool to room temperature and concentrate in vacuo. Purify by chromatography on silica gel (40 g) eluting with hexane/EtOAc (9:1 to 3:1 over 30 min; 40 mL/min) to obtain the desired intermediate (567 mg, 86%) as an off-white solid. MS (ES+) m/z: 184 (M+H)+.
