tert-butyl N-[(1S)-2-hydroxy-2-methyl-1-phenylpropyl]carbamate

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a solution of (S)-tert-butyl(2-hydroxy-2-methyl-1-phenylpropyl)carbamate (3.5 g, 13 mmol) in CH2Cl2 (20 mL) was added dioxane saturated with HCl gas (10 mL) and the contents were stirred at ambient temperature for 30 min. The volatiles were then removed under reduced pressure and the residue thus obtained was triturated with Et2O to afford (S)-1-amino-2-methyl-1-phenylpropan-2-ol. 1H NMR (300 MHz, DMSO-d6) δ 8.3 (bs, 2H), 7.47-7.37 (m, 5H), 5.34 (s, 1H), 4.1 (bs, 1H), 1.17 (s, 3H), 0.97 (s, 3H). Anal. Calcd. C10H15NO 165.2. Found 166.2 (M+H). The volatiles were then removed under reduced pressure the residue thus obtained was triturated with Et2O
