Yield: 90%
Reaction Conditions:
with aluminum oxide in toluene for 16 h;Heating / reflux;
Steps:
1.40.A
To a solution of 4-amino-3-(4-chlorophenyl)-butanoic acid (baclofen) (1.0 g, 4.7 mmol) in toluene (80 mL) was added neutral alumina (1.4 g, 14 mmol). The mixture was heated to reflux for 16 h, then cooled to room temperature and filtered. The filtrate was evaporated to give the title compound as a white solid (0.82 g, 90%). Exact mass calculated for CioH10ClNO: 195.1, found: LCMS m/z = 196.1 [M+H]+.
