Dimethylcarbamoyl Chloride → 1-((3-chloro-1-(pyridin-3-yl)-1H-pyrazol-4-yl)(ethyl)amino)-1-oxopropan-2-yl dimethylcarbamate

Participants

Reaction Steps

To a stirred solution of N-(3-chloro-1-(pyridin-3-yl)-1H-pyrazol-4-yl)-N-ethyl-2-hydroxypropanamide (0.10 g, 0.34 mmol) in CH2Cl2 (1.1 mL) was added dimethylcarbamic chloride (0.073 g, 0.68 mmol). The reaction mixture was stirred at room temperature for 16 hours, and then diluted with CH2Cl2, washed with water. The phases were separated, dried and concentrated. The residue was purified by basic alumina gel chromatography eluting with 0%-70% acetone/hexanes to afford the title compound F93 as a light yellow oil (0.11 g, 87%).
