Trifluoroacetic acid → 3,5-Dichlorobenzyl 2-(2-aminoethyl)morpholine-4-carboxylate

Participants

Reaction Steps

A mixture comprising of 3,5-dichlorobenzyl 2-(2-((tert-butoxycarbonyl)amino)ethyl)morpholine-4-carboxylate (step 1)(500 mg, 1.154 mmol) and trifluoroacetic acid (3556 μl, 46.2 mmol) in DCM (3.8 ml) was stirred for 1 hour at room temperature. The resulting mixture was concentrated under reduced pressure and the crude product was diluted with EtOAc. The mixture was washed with sat. NaHCO3 and the organic portion was separated, dried over MgSO4, filtered and concentrated under reduced pressure to afford the title compound;
