5A. Preparation of Formula (c) A mixture of 1,3-dichloro-2-propanol (10 gm) and paraformaldehyde (3.02 gm) in dichloromethane (100 ml) was cooled to -5° C., and gaseous hydrogen chloride bubbled into the mixture over 25 minutes. The resultant mixture was kept at -8° C. for 14 hours. Sodium sulfate (2 gm) was then added, and the mixture stirred at room temperature for 2 hours. The solid was filtered off, and the filtrate washed with 20% aqueous sodium hydroxide (2*20 ml), and the aqueous phase removed. Solvent was removed from the organic phase under reduced pressure, giving 2-(chloromethoxy)-1,3-dichloropropane as a colorless liquid (13.21 gm, 96.1% yield).
