Chemical Properties

Off-white powder

Uses

peptide synthesis

reaction suitability

reaction type: solution phase peptide synthesis

Synthesis

A solution of compound (S)-acetyl-protected raw material (10 g, 0.048 mol) in 10% aqueous hydrochloric acid (100 mL) was stirred at 95-100 C for 6 h and then the pH was neutralized with triethylamine. The solid was collected by filtration and washed with water (40 mL) to afford the deacetylation product-like white solid L-4-bromophenylalanine. (Yield 68.4%)
