Reaction Steps

In a 25 mL round-bottomed flask, 7H-pyrrolo[2,3-d]pyrimidine-5-carbonitrile (40.9 mg, 284 μmol, Eq: 1.00), 6-tert-butyl-8-fluoro-2-(1-hydroxy-1,3-dihydrobenzo[c][1,2]oxaborol-4-yl)phthalazin-1(2H)-one (100 mg, 284 μmol, Eq: 1.00), copper acetate (34.8 mg) and pyridine (44.9 mg, 45.9 μl, 568 μmol, Eq: 2) were combined with dichloroethane to give a dark blue suspension. The reaction mixture was flushed with nitrogen. The reaction mixture was heated to 80° C. and stirred for 16 hr. The reaction was diluted with sat NH4Cl (50 mL) and extracted with EtOAc (3×50 mL). The mixture was separated by flash column using 30-50% EtOAc in hexanes to give the 7-[3-(6-tert-Butyl-8-fluoro-1-oxo-1H-phthalazin-2-yl)-2-hydroxymethyl-phenyl]-7H-pyrrolo[2,3-d]pyrimidine-5-carbonitrile (42 mg, 31%) as a lyophilized white powder.
