Versuchsvorschrift

A reaction mixture of 5-(4-fluoro-phenyl)-6-piperazin-1-yl-pyrimidin-4-ylamine (400.0 mg; 1.46 mmol; 1.00 eq.), 4,5-dichloro-2-hydroxy-benzaldehyde (279.5 mg; 1.46 mmol; 1.00 eq.), Acetic acid (87.8 mg; 1.46 mmol; 1.00 eq.) and sodium triacetoxy borohydride (926.1 mg; 4.39 mmol; 3.00 eq.) in DCE (10 ml) was stirred overnight at RT. The reaction solution was diluted with DCM and washed with brine. The organic layer was dried and concentrated, which was added 10 ml of ether and stirred for 5 mins. The precipitate was filtered to afford the title as white off solid (528 mg, yield 80.5%). LC-MS: (M+1=448, obsd.=448/450).
