Procedure

2-Bromo-6-(8-tert-butyl-5-oxo-1,2,3,5-tetrahydrobenzo[e][1,4]diazepin-4-yl)-benzaldehyde (0.100 g, 0.23 mmol),1-Methyl-3-[5-(morpholine-4-carbonyl)-pyridin-2-ylamino]-5-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-1H-pyridin-2-one (0.091 g, 1.0 eq), xantphos (12 mg, 0.09 eq), and potassium phosphate (0.096 g, 2 eq) were taken up in n-butanol (3 mL) and water (0.5 mL) and a stream of argon was bubbled through the mixture for 1 minute. Pd(dba)2 (0.008 g, 0.06 eq) was added and argon was bubbled through for an additional minute. The reaction was heated under argon and stirred at 100° C. for 3 hours. The reaction was cooled, solvent was removed under vacuum, and placed directly on a silica gel column, eluted with 100% ethyl acetate, then 4% MeOH in CH2Cl2 to give the title compound as a brown solid, 76 mg as a 60:40 mixture (the title compound as the major component) with an impurity and used without further purification.
