Procedure

2-Acetylamino-2-(9-tert-butoxycarbonyl-9H-carbazol-3-ylmethyl)-malonic acid diethyl ester (200 mg, 0.4 mmol) was combined with hydrogen bromide (4 mL of a 24% aqueous solution) and refluxed for about 12 h. The cooled reaction mixture was evaporated under reduced pressure and dried under high vacuum to afford the amino acid as the hydrogen bromide salt. ES-MS (M+H)+ 255.0 (calc. 254.1).
