実験手順: 3-Bromo-4-phenylpyridine (125 mg, 0.534 mmol) was added to a suspension of 2,2′-bis(diphenylphosphino)-1,1′-binaphthyl (BINAP) (33 mg, 0.053 mmol) and tris(dibenzylideneacetone)dipalladium(0) (Pd2(dba)3) (49 mg, 0.053 mmol) in toluene (5 mL). 5-Amino-2-butylisoindolin-1-one (120 mg, 0.587 mmol) and sodium tert-butoxide (128 mg, 1.335 mmol) were added and the mixture was stirred and heated in the microwave (120° C., 300 W, 75 min). Water and ethyl acetate were added, the organic layer was separated and the aqueous layer was extracted with ethyl acetate. The combined organic layers were washed with water and dried over MgSO4. Purification by flash chromatography (dichloromethane/methanol, gradient 1-5% methanol) provided 2-butyl-5-(4-phenylpyridin-3-ylamino)isoindolin-1-one (56 mg, 46%). ESI-MS [M+H]+=358.2. the organic layer was separated the aqueous layer was extracted with ethyl acetate The combined organic layers were washed with water dried over MgSO4 Purification by flash chromatography (dichloromethane/methanol, gradient 1-5% methanol)

実験手順: 5-Amino-2-butylisoindolin-1-one (49.5 mg, 0.242 mmol) was added to a solution of N-(3-formylpyridin-4-yl)pivalamide (50 mg, 0.242 mmol) in acetic acid (1 mL). After stiffing for 5 days, water and sat aqueous NaHCO3 solution were added. The mixture was extracted with EtOAc, the combined organic layers were washed with water, dried over MgSO4 and the solvent was removed in vacuo. The residue obtained was dissolved in MeOH (3 mL) and NaBH4 (18.3 mg, 0.485 mmol) was added. After stirring overnight, water and sat. aqueous NaHCO3 solution were added. Extraction with EtOAc, washing of the combined organic layers with water and drying over MgSO4 provided the crude product which was purified by HPLC (24 mg, 19%). ESI-MS [M+H]+=395.2. were added The mixture was extracted with EtOAc the combined organic layers were washed with water dried over MgSO4 the solvent was removed in vacuo The residue obtained Extraction with EtOAc washing of the combined organic layers with water drying over MgSO4

実験手順: 5-Amino-2-butylisoindolin-1-one (48.1 mg, 0.236 mmol) was added to a solution of 4-(benzylamino)nicotinaldehyde (50 mg, 0.236 mmol) in acetic acid (0.5 mL). Sodium triacetoxyborohydride (100 mg, 0.471 mmol) was added and the reaction mixture was stirred for 2 days. After the addition of more triacetoxyborohydride (50 mg, 0.235 mmol) and stirring for 6 h, water and sat aqueous NaHCO3 solution were added. The mixture was extracted with EtOAc, the combined org. layers washed with water and dried (MgSO4). Purification by HPLC provided 5-((4-(benzylamino)pyridin-3-yl)methylamino)-2-butylisoindolin-1-one (16 mg, 13%). ESI-MS [M+H+]=401.2. stirring for 6 h were added The mixture was extracted with EtOAc layers washed with water dried (MgSO4) Purification by HPLC

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%).
