Reaction Steps
To a solution of rac-3,6-diaza-bicyclo[3.2.0]heptane-3-carboxylic acid 2,4-dichloro-benzylamide (150 mg, 270 μmol) in toluene (6 mL) were added 2-bromopyrimidine (43 mg, 270 mmol) and triethylamine (27 mg, 270 μmol). After addition of tris(dibenzylideneacetone)dipalladium(0) (5 mg, 5 μmol), BINAP (10 mg, 16 μmol) and potassium tert-butylate (30 mg, 270 μmol) the reaction mixture was heated under an argon atmosphere to 110° C. for 20 h. It was filtered and concentrated in vacuo. Purification by chromatography (SiO2; dichloromethane:methanol 1:0 to 9:1) afforded the title compound (26 mg, 25%) as a white solid. MS (EI) m/e: 378.3 (M+H)+.
