Benzoyl chloride, 3,4-dichloro- → HCID 22807733, compound

Participants

Reaction Steps

This titled benzamide was prepared according to the general acid chloride method described above on a 0.01 mol scale by reacting the trans-2-[N-(2-furylmethyl)methylamino]cyclohexylamine, prepared as described in part (a) above with 3,4-dichlorobenzoyl chloride. The reaction product mixture was extracted with methylene dichloride to extract the benzamide product therefrom. The crude product was chromatographed on 380 g. of silica gel using a 1 percent methanol-in-chloroform eluant. Fraction 1 (1000 m.) and fractions 2 to 17 (25 ml. each) gave no material. Fractions 18 to 54 (25 ml. each) gave a solid which was crystallized from ether giving colorless needles, 1.91 g., (50% yield) of the named benzamide product, melting point 149°-150° C. The Ultraviolet, Infrared, and Nuclear Magnetic Resonance spectral analyses were consistent for the named benzamide.
