Reaction Steps

To a solution of N′-[4-[(3aR*,7S*,7aS*)-3-(3-tert-butyl-benzyl)-2,5,5-trioxo-octahydro-1-oxa-5lambda*6*-thia-3-aza-inden-7-ylmethyl]-2-fluoro-6-((S)-3,3,3-trifluoro-2-hydroxy-propyl)-phenyl]-N,N-dimethyl-formamidine (0.095 g, 0.144 mmol) in anhydrous DMF was added under argon NaH (0.008 g, 0.34 mmol, 95%) and after 20 min stirring methyliodide (0.028 mL, 0.44 mmol). The reaction mixture was stirred for 2 h at 25° C. After addition of saturated aq. NaHCO3 solution the title compound was extracted with EtOAc. The crude compound, a light yellow oil, was used as such in the next step: TLC (EtOAc) Rf=0.47; HPLC RtA=2.06 min; ESIMS [M+H]+=642.
