Reaction Steps

A sealable vial was charged with N-(3-((4S,6S)-2-amino-4-(fluoromethyl)-6-(trifluoromethyl)-5,6-dihydro-4H-1,3-oxazin-4-yl)-4-fluorophenyl)-5-chloro-3-methylpicolinamide (Example 4, 0.068 g, 0.147 mmol) and toluene (1 mL). 2,4-Bis(4-methoxyphenyl)-2,4-dithioxo-1,3,2,4-dithiadiphosphetane (0.059 g, 0.147 mmol) was added and the reaction mixture was heated to 120° C. overnight. Upon cooling to room temperature, the reaction mixture was taken up in EtOAc (75 mL). The organic layer was washed with aqueous saturated NaHCO3 and with brine, dried over MgSO4 and concentrated under reduced pressure. The residue was purified through silica gel (gradient 30%-50% EtOAc-hexane) affording the title compound as a yellow solid (8.4 mg, 0.018 mmol, 12%). MS m/z=479 [M+H]+. Calculated for C19H16ClF5N4OS: 478.
