反应详情

To a solution of 2-(methylamino)ethanol (600 mg, 7.99 mmol) in THF (5.0 mL) was added 2-chlorobenzylisocyanate (0.75 mL, 6.66 mmol). The reaction was stirred at rt for 30 min. The mixture was concentrated, re-dissolved in MeOH, filtered, and purified on RP-HPLC using a mixture of acetonitrile and H2O to give 3-(2-chlorobenzyl)-1-(2-hydroxyethyl)-1-methylurea (950 mg, 49%). LRMS (M+H+) m/z 243.0.
