benzyl N-[(1S)-2-(dimethylamino)-2-oxo-1-phenylethyl]carbamate

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

Procedure: A suspension of 1.67 g of the compound obtained in Step 87-1 and 0.17 g of 10% palladium-carbon in EtOH (20 ml) was stirred at room temperature for 14 hours under hydrogen atmosphere. The stirred solution was added with THF (1 ml) and stirred at room temperature for 1 hour under hydrogen atmosphere. The insoluble matter was separated by filtration and the filtrate was concentrated under reduced pressure to obtain 0.97 g of the title compound (pale yellow solid, crude form). stirred at room temperature for 1 hour under hydrogen atmosphere The insoluble matter was separated by filtration the filtrate was concentrated under reduced pressure
