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 (334.0 mg; 1.260 mmol) and 3-(2,4-difluoro-3-methyl-phenyl)-propionaldehyde (232.7 mg; 1.260 mmol) afforded 8-[2-(2,4-difluoro-3-methyl-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.
