実験手順

According to the general procedure (GP10), the microwave-assisted Pictet-Spengler reaction (60 W; 100° C.; 8 bars; 10 min.) between 2-(2-ethyl-4-iodo-imidazol-1-yl)-ethylamine (344.6 mg; 1.300 mmol) and 3-(3,4-dimethyl-phenyl)-propionaldehyde (211.4 mg; 1.300 mmol) afforded 8-[2-(3,4-dimethyl-phenyl)-ethyl]-3-ethyl-1-iodo-5,6,7,8-tetrahydro-imidazo[1,5-a]pyrazine which was Boc-protected and finally purified by HPLC.
