Reaction Steps

Synthesized according to general procedure 8. The reaction was set up with 4-bromo-N-(pyrimidin-4-yl)benzenesulfonamide (2.4 mmol), (S)-2-methylpiperazine (4.7 mmol), Pd2(dba)3 (0.12 mmol), 2-(di-t-butylphosphino)biphenyl (0.50 mmol), NaO-tBu (10 mmol), and toluene (12 mL). For the purification, 10% MeOH in CH2Cl2 with the addition of 1% triethylamine was used as a solvent system to obtain the desired amine as a white solid (300 mg, 38% yield). LC/MS (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA)), m/z: M+1 obs=334.3; tR=0.39 min.
