An isopropyl alcohol (25 ml) solution of tert-butyl (1S)-2-(3,5-difluorophenyl)-1-[(2S)-oxiran-2-yl]ethylcarbamate (2.2 g, 7.2 mmol) and 6-Iodo-chroman-4-ylamine (3.0 g, 10.9 mmol) was stirred at 75° C. for 0 h. The IPA was removed in vacuo and the resulting residue dissolved in EtOAc (200 ml). The organic layer was washed with 1 N HCl (4×50 ml), followed by NaHCO3 (2×50 ml), and brine (1×50 ml). The organic layer was dried over Na2SO4 and concentrated in vacuo to yield 3.5 g (85%) of the title compound as an off white solid. MS (ESI+) for C24H29F2IN2O4 m/z 574.8 (M+H)+.
