The reaction of 4-(trifluoromethyl)styrene (I) with mCPBA in dichloromethane gives the epoxide (II), which is treated with MeONa in methanol to yield the benzyl alcohol (III). The reaction of (III) with MsCl and TEA affords the mesylate (IV), which is condensed with the monoprotected piperazine (V) in refluxing acetonitrile to provide a diastereomeric mixture of compounds (VI) + (VII) that is resolved by flash chromatography. The desired isomer (VII) is deprotected by means of HCl or TFA to give piperazine (VIII), which is condensed with N-Boc-4-piperidone (IX) with simultaneous alkylation by means of Ti(OiPr)4 and Et2Al-CN in refluxing dichloromethane to yield the intermediate (X). The reaction of (X) with MeMgBr in THF affords the methylated compound (XI), which is deprotected by means of TFA to provide the substituted piperidine derivative (XII). Finally, this compound is acylated by means of 4,6-dimethylpyrimidine-5-carbonyl chloride (XIII) and aqueous NaOH in dichloromethane to provide the target compound. (1-3)

The reaction of the chiral benzyl alcohol (I) with 4-chlorobenzenesulfonyl chloride (II) and DABCO in toluene gives the sulfonate (III), which is condensed with the monoprotected piperazine (IV) by means of K2CO3 in hot toluene/acetonitrile to yield the adduct (V). The deprotection of (V) by means of hot aqueous HCl affords the piperazine derivative (VI), which is condensed with the acyl piperidine (VII) --obtained by condensation of 4,6-dimethylpyrimidine-5-carboxylic acid (VIII) with 4-piperidone (IX) --by means of acetone cyanohydrin or NaCN/AcOH to provide the cyano adduct (X). Finally, this compound is treated with AlMe3 and Me-MgCl in THF/toluene to yield the target compound.
