Procedure

To a solution of (3S,5S,6R,8S)-8-allyl-6-(3-chlorophenyl)-5-(4-chlorophenyl)-3-ethyl-8-methyl-2,3,5,6,7,8-hexahydrooxazolo[3,2-a]pyridin-4-ium trifluoromethanesulfonate (86 mg, 0.15 mmol; Example 339, Step A) in DMF (0.74 ml) was added sodium ethanethiolate (38 mg, 0.45 mmol). After being stirred at 25° C. for 1.5 h, the reaction was quenched (sat. aq. NH4Cl), extracted (2×EtOAc), and washed (2× brine). The combined organic layers were dried over Na2SO4, filtered and the filtrate was concentrated under reduced pressure. Purification of the residue by chromatography on silica gel (12 g SiO2, 10% and 20% EtOAc/hex) provided the title compound as a colorless liquid.
