General procedure for the synthesis of β-chlorobutanone from 4-hydroxy-2-butanone: 4-hydroxy-2-butanone (0.881 g, 10 mmol), dichloromethane (2 ml), and thionyl chloride (1.46 ml, 20 mmol) were added in a reaction flask and the reaction was stirred at room temperature overnight. Upon completion of the reaction, the solvent was removed by rotary evaporator and the residue was dried with a stream of nitrogen to give 2-chlorobutan-2-one (1.06 g). The product was characterized by 1H-NMR (400 MHz, DMSO-d6): δ 2.12 (s, 3H), 2.94 (t, 2H), 3.74 (t, 2H). | [References]
