Reaction Steps

Dissolve 8.50 g (55 mmol) of 4-nitrothiophenol in 40 mL of dimethylformamide and make basic with 13.7 mL of 4N potassium hydroxide. Add 10.60 g (60 mmol) of N-[3-chloropropyl]-4-methylpiperidine and heat this solution to 100° C. for 3 h. After this time cool the reaction to room temperature. Add 200 mL of water and extract with 2×150 mL of methylene chloride. Acidify the combined organic extracts to pH=1 with 1N hydrochloric acid and extract with 4×150 mL of water. Neutralize the combined aqueous extracts with saturated sodium bicarbonate solution and extract with 3×200 mL of methylene chloride. Dry the organic extracts over anhydrous sodium sulfate. Filter the drying agent and remove the solvent in vacuo to provide the title compound.
