Versuchsvorschrift
Followed the procedure described in Compound W-8 step 1, starting with 3-chloro-7-methoxyisoquinoline (Intermediate 12) and 4-boronobenzoic acid with an alternative isolation procedure: After reaction was complete, the reaction mixture was diluted with H2O (10 mL). The aqueous layer was extracted with EtOAc/MeOH (v/v=10:1, 30 mL×2). Then the aqueous layer was acidified with 2M HCl to pH=6. The precipitate was collected by filtration and washed with MeOH (10 mL), dried under high vacuum to give the product.
