Synthesis of Cbz-GlyNH₂
The synthesis of Cbz-GlyNH₂ was adapted from a previously reported protocol
[19]
.
Glycinamide hydrochloride (18 mmol, 2.00 g) was dissolved in water (60 mL) and acetone (8 mL), prior to the addition of Na₂CO₃ (54 mmol, 5.7 g) and NaHCO₃ (18 mmol, 1.5 g).
Benzyl chloroformate (22 mmol, 3.20 mL) was added dropwise to the stirring solution over the course of 30 min.
The resulting mixture was stirred for 3 h at room temperature, after which the products were isolated by washing with diethyl ether (50 mL).
The protected product was precipitated out of solution by the slow addition of 0.1 M HCl.
The precipitate was filtered and subsequently dried in vacuo to afford a white solid in 86% yield (3.24 g).
¹H NMR (CDCl₃, 400 MHz): δ 3.87 (s, 2H), 5.07 (s, 2H), 7.26 (m, 5H), 7.35 (s, 2H), 7.95 (s, 1H).
¹³C NMR (CDCl₃, 100 MHz): δ 45.1, 67.3, 126.2, 126.9, 128.9, 136.3, 156.8, 170.1. HRMS (ESI) calculated for C₁₀H₁₂N₂O₃: 208.0848. Found: 208.0851.
