Ethyl Acetate → 1-(3-Chloro-propyl)-3-(4-methyl-pyridin-3-yl)-urea

関与物質

反応手順

1-Chloro-3-isocyanato-propane (1.6 g, 13.87 mmol) was added dropwise to a stirred solution of 4-methyl-pyridin-3-ylamine (1 g, 9.25 mmol) in toluene (15 mL) at 0° C. The reaction mixture was stirred at room temperature for 18 hours. The reaction was monitored by TLC (100% ethylacetate). The reaction mixture was filtered, washed with toluene and dried under reduced pressure to afford 2.12 g (99.5% yield) of 1-(3-chloro-propyl)-3-(4-methyl-pyridin-3-yl)-urea.
