Trimethylsilyl isocyanate → HCID 9904992, compound

Participants

Reaction Steps

To a solution of 3-(3-(4-fluorophenoxy)phenyl)-1-cyclobutylhydroxylamine from above in THF (50 mL) was added trimethylsilylisocyanate (1.64 g of 85% purity, 12.12 mmol) and the reaction was stirred for 10 min. It was then concentrated in vacuo. The resulting residue was chromatographed (silica gel; ether, methanol 96:4 to 90:10) to afford 1.60 g (50% over three steps) of N-[3-(3-(4-fluorophenoxy)phenyl)-cyclobutyl]-N-hydroxyurea as a 1:1 mixture of diastereomers.
