A: Dissolve about mg in 5 to 10 mL of water in a separator, add 4 mL of 6 N ammonium hydroxide, and extract with four mL portions of chloroform. Combine the chloroform extracts, evaporate with the aid of a current of warm air, and dry the residue in vacuum over silica gel for 24 hours: the crystalline precipitate so obtained responds to the Identification tests under Lidocaine.
