Reaction Steps

0.20 g (0.73 mmol) 7-methoxy-3-piperidin-4-yl-1,3,4,5-tetrahydro-1,3-benzodiazepin-2-one and 0.14 mL (0.80 mmol) DIPEA were placed in 3.0 mL DMF. 0.17 g (0.74 mmol) tert. butyl 6-chloro-5-methyl-pyrimidine-4-carboxylate were added and the reaction mixture was stirred for 3 h at RT. The reaction mixture was mixed with water and extracted with DCM. The organic phase was dried, filtered and concentrated to dryness by rotary evaporation. The residue was combined with diisopropylether and the precipitated solid was suction filtered and dried.
