Participants

Reaction Steps

According to the general procedure (GP10), the microwave-assisted Pictet-Spengler reaction (60 W; 110° C.; 6 bars; 10 min.) between 2-(4-iodo-2-methyl-imidazol-1-yl)-ethylamine (758 mg; 3.020 mmol) and 3-(3,4-dimethyl-phenyl)-propionaldehyde (490 mg; 3.020 mmol) afforded 8-[2-(3,4-dimethyl-phenyl)-ethyl]-1-iodo-3-methyl-5,6,7,8-tetrahydro-imidazo[1,5-a]pyrazine which was Boc-protected and finally purified by FC (DCM/MeOH=25/1).
