反应详情

To a solution of 3-amino-N-(2-chlorobenzyl)-2,2-dimethylpropanamide (0.45 mmol) in DCM (5 mL) was added DIEA (157 μL, 0.90 mmol, 2 equiv.) and 4-ethylphenyl isocyanate (97.0 μL, 0.675 mmol, 1.5 equiv.). The reaction mixture was stirred for 30 min. The mixture was concentrated and purified on RP-HPLC using a mixture of acetonitrile and H2O to give N-(2-chlorobenzyl)-3-(3-(4-ethylphenyl)ureido)-2,2-dimethylpropanamide (29.6 mg, 17% for two steps). LRMS (M+H+) m/z 388.1.
