Reaction Steps

To a solution of 1-isopropyl-7-(methylthio)-1,2,3,4-tetrahydropyrazino[1,2-a]indole (50 mg, 0.19 mmol) in PrOH (2 mL) was added 2-chloro-4-(trifluoromethyl)pyrimidine (105 mg, 0.58 mmol) and DIEA (185 mg, 0.96 mmol). The mixture was stirred at 100° C. for 4 h. The mixture was concentrated under vacuum and the residue was purified by preparative TLC to afford 1-isopropyl-7-(methylthio)-2-(4-(trifluoromethyl)pyrimidin-2-yl)-1,2,3,4-tetrahydropyrazino[1,2-a]indole (45 mg, 57.7% yield) as a yellow oil. LC-MS MS (ESI) m/z 407.1 [M+H]+.
