実験手順
1-(3-Chloro-propyl)-3-(4-methyl-pyridin-3-yl)-urea (I-130a: 2 g, 9.25 mmol) in dry DMF (15 mL) was added to a stirred mixture of sodium hydride (330 mg, 13.87 mmol) in THF (30 mL) at 0° C. The reaction was stirred at room temperature for 1 hour. The reaction was monitored by TLC (100% ethylacetate). The reaction mixture was quenched with MeOH at 0° C., concentrated under reduced pressure and partitioned between ice water and chloroform. The organic layer was washed with brine solution, dried over Na2SO4 and concentrated under reduced pressure to afford 1.7 g (96.5% yield) of 1-(4-methyl-pyridin-3-yl)-tetrahydro-pyrimidin-2-one.
