Participants

Reaction Steps

To a solution of 1-isopropyl-7-(methylthio)-1,2,3,4-tetrahydropyrazino[1,2-a]indole (100 mg, 0.38 mmol) and DIPEA (248.3 mg, 1.921 mmol) in i-PrOH (3 mL) was added ethyl 2-chloro-4-(trifluoromethyl)pyrimidine-5-carboxylate (196 mg, 0.77 mmol). The reaction mixture was stirred at rt overnight. The mixture was concentrated and purified by preparative TLC on silica gel eluting with PE/EtOAc 1:1 to afford ethyl 2-(1-isopropyl-7-(methylthio)-3,4-dihydropyrazino[1,2-a]indol-2(1H)-yl)-4-(trifluoromethyl)pyrimidine-5-carboxylate (60 mg, 32.6% yield) as a colorless oil. LC-MS MS (ESI) m/z 478.7 [M+H]+.
