Versuchsvorschrift

1-Boc-4-(2-chloropyridin-4-ylmethyl)piperazine (500 mg, 1.63 mmol) (Preparation B-14) was mixed with 3-aminoisoquinoline (234 mg, 1.0 equiv), Pd2(dba)3 (148 mg, 0.1 equiv), xantphos (140 mg, 0.15 equiv), and Cs2CO3 (735 mg, 1.4 equiv) in toluene. The mixture was refluxed overnight, and EtOAc was added in to dilute the mixture. After filtration, the filtrate was concentrated and applied onto a silica gel column. The title compound (250 mg, yield 61%) was obtained as yellow solid.
