Methyl Isocyanate → HCID 16225956, compound

Participants

Reaction Steps

To a solution of C—[(R)-7-(3-Fluoro-benzenesulfonyl)-chroman-2-yl]-methylamine (0.130 g, 0.405 mmol) in methylene chloride (10 mL) at 0° C. was added methyl isocyanate (0.115 g, 2.03 mmol). The mixture was stirred at room temperature for one hour, and was then quenched by addition of MeOH. The mixture was partitioned between water and methylene chloride, and the organic phase was washed with water and brine, dried (Na2SO4), filtered and contrated under reduced pressure. Purification of the residue by flash chromatography (hexanes:EtOAc 1:9) gave 0.153 g of 1-[(R)-7-(3-fluoro-benzenesulfonyl)-chroman-2-ylmethyl]-3-methyl-urea as a foam. MS (M+H)=379.
