Procedure

A solution of diethyl 2-[(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)methyl]-2-(phenylmethyl)butanedioate (13 g, 31.8 mmole) in conc. HCl (125 mL) and HOAc (30 mL) was sealed in a 1 L screwcap reaction vessel and the contents heated to 120° C. for 48 h. The reaction solution was concentrated under vacuum and the resulting solids washed with Et2O affording the title compound (quant.) as a white solid: LCMS (ES) m/z 181(M+H)+.
