Procedure
N,N'-Carbonyldiimidazole (0.37 g) is added to a solution of 2-(tert-butoxycarbonylaminomethyl)phenylacetic acid (0.6 g) in dry dichloromethane (20 cc), cooled to +5° C. The mixture is stirred for 30 minutes at +5° C. and a solution of (3aRS,7aRS)-7,7-diphenyl-4-perhydroisoindolone hydrochloride (0.75 g) and triethylamine (0.6 cc) in dichloromethane (20 cc) is then added. The reaction mixture is stirred at 20° C. for 16 hours, then washed with water (2×100 cc), dried over magnesium sulphate and filtered and the filtrate is concentrated to dryness under reduced pressure (2.7 kPa). (3aRS,7aRS)-2-[(2-(tert-butoxycarbonylaminomethyl)phenyl)acetyl]-7,7-diphenyl-4-perhydroisoindolone (105 g) is obtained in the form of a white meringue.
