合成路线1
该中间体在本合成路线中的序号:(I)Adamantane-1-carboxylic acid chloride (freshly prepared from the reaction of thionyl chloride (I) with the adamantane-1-carboxylic acid) was reacted with 1-(2-aminoethyl)-4-(2-pyrimidinyl)piperazine (II) in CH2Cl2 in the presence of triethylamine (TEA) to afford Wy-50,324 free base in 70% (III) yield which was converted to the hydrochloride salt using ethanolic HCl solution.

合成路线2
该中间体在本合成路线中的序号:(II)Condensation of (S)-3-amino-1-benzylpyrrolidine (I) with 1-adamantanecarbonyl chloride (II) by means of Et3N in dichloromethane affords amide (III), which is then debenzylated by hydrogenolysis over Pd/C and hydrazine monohydrate to provide amine (IV). Subsequent N-alkylation of (IV) with tosylate (V) in acetonitrile in the presence of K2CO3 furnishes the corresponding alylated compound (VI), which is finally converted into the desired hydrochloride monohydrate derivative by first treatment with HCl:isopropanol in ethyl acetate followed by recrystallization in EtOH:H2O using activated carbon.
