Procedure

To a solution of 2-(((2S,3R)-3-methylpiperidin-2-yl)methyl)isoindoline-1,3-dione (100 mg, 387 μmol) in DMF was added DIPEA (202 μL, 1.16 mmol) followed by 5-(4-fluorophenyl)-2-methylthiazole-4-carboxylic acid (137 mg, 580 μmol) and HATU (176 mg, 465 μmol). The reaction was allowed to stir at rt for 15 h, and was then concentrated in vacuo to remove the DMF. The crude residue was taken up in EtOAc and washed with 1 M HCl, sat aq. NaHCO3, brine, dried (MgSO4), and concentrated. The crude residue was purified by chromatography on silica gel (EtOAc/hexanes) to give 2-(((2S,3R)-1-(5-(4-fluorophenyl)-2-methylthiazole-4-carbonyl)-3-methylpiperidin-2-yl)methyl)isoindoline-1,3-dione as a light yellow oil (130 mg, 71%). MS (ESI) 478 (M+H).
