2-Phenylacetamide synthesis

13synthesis methods
Synthesis of 2-phenylacetamide: Add concentrated hydrochloric acid to phenylacetonitrile, stir to dissolve, and react at 50°C for half an hour. Then slowly add water under cooling to separate out crystals, filter after cooling, wash with ice water to obtain crude product. The crude product was washed with sodium carbonate solution, then washed with ice water, and dried to obtain purer phenylacetamide.

Yield:103-81-1 100%

Reaction Conditions:

with Acetaldehyde oxime in methanol at 65; for 4 h;

Steps:



General procedure: A typical reaction was carried out in a 10 mL flask. Benzonitrile (2 mmol), CuII-4 ? (0.2 g), acetaldoxime (6 mmol) and MeOH (4 mL) were stirred at 65 °C for 4 h. The solid was filtered, washed with MeOH and the filtrate evaporated. The residue was subjected to GC-MS analysis and NMR spectroscopy. The filtered catalyst can be recycled after drying at about 150 °C for 1 h.
