5-amino-2-butylisoindolin-1-one (35.0 mg, 0.17 mmol), ZnCl2 (14.0 mg, 0.10 mmol) and NaCNBH4 (12.9 mg, 0.21 mmol) were consecutively added to a solution of 4-(trifluoromethyl)nicotinaldehyde (30.0 mg, 0.17 mmol) in MeOH (4 mL). After stirring overnight at room temperature excess water was added. The reaction mixture was extracted with EtOAc, the combined org. layers were washed with water, dried (MgSO4) and the solvent was removed in vacuo. Purification by HPLC provided 2-butyl-5-((4-(trifluoromethyl)pyridin-3-yl)methylamino)isoindolin-1-one TFA (16.0 mg, 19%). ESI-MS [M+H]+=364.2.
