Reaction Steps

A −20° C. solution of (S)-1-(2-chloroethyl)-3-(1-methoxypropan-2-yl)urea (393 mg, 2.019 mmol) in THF (10 mL) was treated portion-wise with NaH (60% in mineral oil, 178 mg, 4.44 mmol), warmed to RT and stirred overnight. The mixture was treated with EtOAc, washed with water, then brine, dried over Na2SO4 and concentrated to dryness to afford crude (R)-1-(1-methoxypropan-2-yl)imidazolidin-2-one (100% yield assumed) which was used without further purification. MS (ESI) m/z: 159.1 (M+H+).
