Sodium Hydroxide → 4-(Chloro(4-chlorophenyl)methyl)-1-methylpiperidine

Participants

Reaction Steps

To a solution of 4-chlorophenyl 1-methylpiperidin-4-yl methanol 1.2 g (5.02 mmol) in toluene (5 ml) was added thionyl chloride (0.45 ml) dropwise. The resulting mixture was stirred at room temperature over night. The mixture was then made alkaline with NaOH solution and extracted with ethyl acetate (3×40). The combined organic solution was dried and concentrated to give 1.2 g of desired product.
