2-[(2S)-2-amino-3-phenylpropyl]isoindole-1,3-dione

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a solution of 1,1-dimethylethyl[(1S)-2-(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)-1-(phenylmethyl)ethyl]carbamate (4.3 g, 11.3 mmole) in MeOH (100 mL) at RT was added 4M HCl in dioxane (50 mL). After stirring for 3 h at RT, the reaction solution was concentrated to a white solid (quant.): LCMS (ES) m/z 281 (M+H)+. the reaction solution was concentrated to a white solid (quant.)

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.
