Pentane → HCID 15670863, compound

Participants

Reaction Steps

Pentane (50 mL) was added to sodium hydride (0.50 g, 11 mmol of 50% suspension in mineral oil) and the mixture was stirred under nitrogen. The pentane was decanted. Anhydrous DMF (12 mL) was added and the suspension was cooled to 0° C. [Bis(4-fluorophenyl)methylpiperazine (2.9 g, 10 mmol) was added in anhydrous DMF (14 mL) at 0° C. within 10 min. The reaction mixture was allowed to warm to room temperature. After 1 h, the mixture was cooled to 0° C. and 1-chloro-3-bromopropane (5 mL, 50 mmol) in anhydrous DMF (5 mL) was added to the fight green solution over a period of 10 min. The mixture was stirred under nitrogen at room temperature for 72 h. The solvents were evaporated in vacuo (1 mm Hg) at 50° C. The residue was triturated in methylene chloride and filtered through Celite. The filtrate was washed with water (2× 100 mL), dried (sodium surfate), filtered, and the filtrate evaporated in vacuo to give crude chloropropyl compound (3.65 g). Pentane (50 mL) was added, and on the next day the pentane insoluble solid was filtered. The filtrate was evaporated in vacuo to give title compound (2.3 g, 75%) as a clear, colorless oil. 100 MHz 1H MR (CDCl3)δ7.32 (m, 4H), 6.95 (m, 4H), 4.2 (s, 1H), 3.57 (m, 2H), 2.2-2.6 (m, 10H), 1.9 (m, 2H). DCI/MS (M+1) 361.
