実験手順

A solution of (R)-2-(3-oxo-1-tosyl-1,2,3,4-tetrahydropyrazin-2-yl)acetic acid (310 mg, 1.0 mmol), crude (R)-6-(2-(piperidin-1-yl)ethyl)-1,2,3,4-tetrahydronaphthalen-1-amine (310 mg, 1.2 mmol), HOBt (135 mg, 1.0 mmol) and EDCI (191 mg, 1.0 mmol) in 1 mL of DMF was stirred overnight at room temperature. After quenching with sat. NaHCO3 solution, the reaction mixture was extracted with EtOAc. The combined organic phase was washed brine, dried over Na2SO4, and evaporated in vacuo. Flash chomatography (SiO2, EtOAc/MeOH=100:15 to 100:20 to EtOAc/2.0M NH3 in MeOH=100:10 to 100:15 to 100:20 ) gave the desired product as a white solid. MS: 551.2 (M+1).
