Participants

Reaction Steps

To a solution of 2-((6S)-4-(4-chlorophenyl)-2,3,9-trimethyl-6H-isoxazolo[5,4-c]thieno[2,3-e]azepin-6-yl)acetamide (Compound 110, 0.120 g, 0.30 mmol) in THF (5 mL) was added Lawesson reagent (0.248 g, 0.60 mmol). The mixture was refluxed overnight. The reaction mixture was concentrated in vacuo and the residue was recrystallized by petroleum and ethyl acetate to give 2-((6S)-4-(4-chlorophenyl)-2,3,9-trimethyl-6H-isoxazolo[5,4-c]thieno[2,3-e]azepin-6-yl)ethanethioamide (0.080 g, 64% yield).
