Trifluoroacetic acid (3 ml) was added to a solution of (R)-tert-butyl (1-(benzylamino)-3-(tert-butyldisulfanyl)-1-oxopropan-2-yl)carbamate (Compound tk92) (1.049 g, 2.63 mmol) in dichloromethane (9 ml), and the reaction solution was stirred at room temperature for 1 hour. The reaction solution was concentrated under reduced pressure and then extracted with ethyl acetate/saturated sodium bicarbonate, and the organic layer was washed with brine. The organic layer was dried over anhydrous sodium sulfate, filtered and then concentrated under reduced pressure to afford (R)-2-amino-N-benzyl-3-(tert-butyldisulfanyl)propanamide (Compound tk93) (810 mg, 100%).
