    Efficient Synthesis of a Highly Selective NPY-5 Receptor Antagonist:  A Drug Candidate for the Treatment of Obesity
    摘要:
    A concise and practical synthesis of highly selective NPY-5 receptor antagonist 1 is described. The animopyrazine intermediate 3 was synthesized via either monobromination of aminopyrazine or palladium-catalyzed regioselective debromination of dibromopyrazine followed by an efficient Suzuki-Miyaura coupling. For the preparation of the spirolactone piperidine 2, significantly improved yield was achieved by using a combination of n-BuMgCl and n-BuLi. This protocol also dramatically increased the thermal stability of the aryllithium intermediate and eliminated the requirement for costly cryogenic conditions. The union of the spirolactone piperidine 2 and aminopyrazine 3 via a carbonyl group was accomplished using phenyl chloroformate delivering the target molecule in high yield.

    A method of exchanging a halogen atom of a halide, which has a group containing an acidic proton and in which one or more halogen atom(s) is/are substituted on a carbon atom of the carbon-carbon double bond, with a metal atom by halogen-metal-exchange reaction and introducing an electrophilic reagent into the carbon atom to which the metal atom is attached. The above method is an industrially excellent method of introducing a substituent by halogen-metal exchange reaction.
