Reaction Conditions

Reaction Steps

A solution of 2-(trifluoromethyl)-10H-phenothiazine (2.04 g, 7.6 mmol) and DMF (16 mL) was mixed with CS2CO3 (7.5 g, 22.9 mmol) and 1-bromo-3-chloropropane (1.1 mL, 11.5 mmol) The reaction mixture was heated at 65° C. for 12 h. Once no starting material was observed by analytical LCMS, EtOAC (250 mL) and brine (250 mL) were added. The organic layer was separated, and the aqueous layer was washed with EtOAC (3×100 mL). The combined organic extracts were washed with brine (2×100 mL), dried over MgSO4, and concentrated to afford the title compound.
