Reaction Steps

2-Nitro-6-[(2S)oxiranylmethoxy]aniline (0.20 g, 0.96 mmol) was dissolved in anhydrous tetrahydrofuran (10 mL). Excess Raney Ni was added and the mixture hydrogenated under an atmosphere of hydrogen overnight. The mixture was filtered through a Celite pad. To the anhydrous tetrahydrofuran solution was added with cooling anhydrous N,N-diisopropylethylamine (0.365 mL) followed by phosgene in toluene (0.525 mL). The solvent was partially removed and the title compound collected by filtration (0.10 g, 0.49 mmol).
