Versuchsvorschrift
A solution of (S)-1-methoxypropan-2-amine (500 mg, 5.61 mmol) in THF (15 mL) was treated with 2-chloroethylisocyanate (592 mg, 5.61 mmol), stirred at RT overnight, then concentrated to dryness. The residue was treated with toluene and concentrated to dryness (twice) to afford (S)-1-(2-chloroethyl)-3-(1-methoxypropan-2-yl)urea (100% yield assumed) as a white solid which was used without further purification. MS (ESI) m/z: 195.1 (M+H+).
