Procedure

A solution of tert-butyl-(2R)-4-((6-bromo-1-oxo-2-(phenylsulfonyl)-1,2-dihydroisoquinolin-4-yl)methyl)-2-(hydroxymethyl)piperazine-1-carboxylate (Example 11e, 2.3 g) in DMF (20 mL) was treated with N-cyclopropyl-3-fluoro-4-methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzamide (1.24 g), Pd-118 (0.08 g) and potassium carbonate (0.86 g) under nitrogen. The resulting mixture was heated at 80° C. for 10 h. The reaction mixture was diluted with water (300 mL), acidified with acetic acid (to pH 5) and extracted with ethyl acetate (300 mL). The organic was dried (MgSO4), filtered and evaporated to afford crude product. Purification (SiO2 chromatography, elution with 1% AcOH in ethyl acetate) afforded the subtitle compound (0.60 g) as a solid.
