Reaction Conditions:

with hydrogenchloride in methanol at 0 - 20; for 8 h;Product distribution / selectivity;

Steps:

3.1

tert-Butyl l-(4-cyanophenyl)-3,3-dimethyl-l-oxobutan-2-ylcarbamate (961 mg, 3.04 mmol) was dissolved in 1.25 M HCl in MeOH at 0 °C and the mixture was stirred at rt for 8 h. The solvent was removed and the residue dried in vacuo to give 4-(2-amino-3,3- dimethyl-butanoyl)-benzonitrile hydrochloride (110 mg, 93%).*H NMR (400 MHz, MeOD) δ ppm 1.02 (s, 9 H) 5.05 (s, 1 H) 7.96 (d, 2 H) 8.20(d, 2 H). MS (ESI) m/z 217.1 [M+H]⁺
