Amylocaine can be synthesized beginning with chloroacetone (1).[3][4][5][6][7]Grignard reaction of chloroacetone with magnesium ethyl bromide gives 1-chloro-2-methyl-butan-2-ol (2). Heating with dimethylamine gives 1-(dimethylamino)-2-methylbutan-2-ol (3). These two steps can also be treated as interchangeable. Esterification with benzoyl chloride completed the synthesis of amylocaine (4).[3][4]
