Versuchsvorschrift
This intermediate was prepared, in an analogous manner as described for intermediate 2, from (S)-benzyl 2-(8-amino-1-bromoimidazo[1,5-a]pyrazin-3-yl)pyrrolidine-1-carboxylate (Intermediate 1e) and commercially available N-2-thiazolyl 4-boronobenzamide to afford the title compound (229 mg, 73.1%).
