         [0008]    The amide coupling step is carried out with azide intermediate II to provide intermediate VIII. This is followed by reaction with the heteroaryl acetylene intermediate III in a suitable solvent such as EtOH, optionally in the presence of a copper salt such as CuSO 4  with an appropriate reductant such as sodium ascorbate, and optionally while heating to provide the desired compound of formula (I).

         [0000]    iii) treating triazole 9 with a suitable chlorinating agent such as oxalyl chloride or thionyl chloride in a suitable solvent such as acetonitrile or NMP containing DMF, and a suitable amine base such as pyridine; and subsequently adding amine

         [0000]    10 or its hydrochloride salt, in a suitable base such as DMAP and pyridine, to produce the product compound Ia:

         [0012]    Haloimidazole 5, can be prepared according to the following general scheme: 
         [0000]    
       
                 
         
             
             
         
       
     
         [0013]    The imidazoles 4 were synthesized according to a modification of the published procedure (Frutos, R. P.; Gallou, I.; Reeves, D.; Xu, Y.; Krishnamurthy, D.; Senanayake, C. H.  Tetrahedron Lett.  2005, 46, 8369). The above published procedure was modified by the introduction of thioamides, such as thioacetamide, as scavenging reagents to facilitate the removal of copper salts. Accordingly, a mixture of nitrile 2 and aminoacetal 3 is treated with a copper salt such as copper (I) chloride, and upon reaction completion, the copper salts are removed by filtration after addition of a thioamide such as thioacetamide, preferably prior to the cyclization of the intermediate amidine with HCl or TFA in an alcoholic solvent such as methanol or ethanol. Treatment of 4 with &lt;1 eq of NBS or NIS under standard conditions provides the 5-haloimidazole 5. Treatment of 4 with &gt;2 eq of NBS or NIS under standard conditions, followed by dehalogenation of the 4,5-dihaloimidazole intermediate with an alkylmagnesium halide salt such as i-PrMgCl provides 4-haloimidazole intermediates 5k and 5k′. Coupling of the desired haloimidazole to trimethylsilylacetylene using a modification of the known Sonogashira coupling (Sonogashira, K.  J. Organomet. Chem.  2002, 653, 46) method provides intermediates such as 6, as shown above in step i). An alternative procedure (eq. 1) for the synthesis of imidazoles from imidates and α-amine-acetals is also known (Lawson, A.  J. Chem. Soc.  1957, 4225) but its application for the synthesis of 4 has not been reported. The Cu-catalyzed synthesis of organic azides from aryl iodides has also been reported (Zhu, W.; Ma, D.  Chem. Commun.  2004, 888), in our case the resulting azide intermediate is not isolated but treated with 8 directly to give 9, as shown above in step ii). The general synthesis of triazoles from alkanes and organic azides has been reported (Feldman, A. K.; Colasson, B.; Fokin, V. V.  Org. Lett.  2004, 6, 3897), but not for a compound such as 9. The final coupling to give particular formula (I) compounds can be accomplished through the acyl chloride intermediate with different reagents (SOCl 2  in NMP, (COCl) 2  in acetonitrile), or using standard peptide coupling conditions (EDCI, mixed anhydrides, etc.).

         [0024]    A mixture of haloimidazole 5, PPh 3  (3 mol %), PdCl 2 (PPh 3 ) 2  (1.5 mol %), CuI (3 mol %), Et 3 N (10 eq) and trimethylsilylacetylene (1.2 eq) was stirred at 50° C. for 10 h. After distilling most of the Et 3 N, MTBE (t-butyl methyl ether) was added and distillation was continued. The mixture was suspended in MTBE and filtered through a pad of silica gel and charcoal to remove solids. 2 M aqueous HCl was added until pH 3. After adding n-Bu 3 P (0.2 eq), the mixture was stirred for 1 h. The organic layer was extracted twice with 2 M aqueous HCl. The combined aqueous layers were basified to pH 10-11 with NH 4 OH and extracted with MTBE. The organic layer was concentrated under vacuum to afford alkyne 6 as oily brown solid. In a different flask, an aqueous solution of NaN 3  (1.2 eq) was added to a mixture of 3-iodo-4-methyl benzoic acid (1.05 eq), L-proline (0.21 eq), Na 2 CO 3  (1.26 eq), CuI (5 mol %), sodium ascorbate (5 mol %) and DMSO. After stirring at 85° C. for 10 h, the reaction mixture was allowed to cool to 20-25° C. Alkyne 6, DMSO and water were added, and the mixture stirred at 75° C. for 1.5 h. After filtering the mixture, the filter was rinsed with NH 4 OH. The filtrate was poured onto a stirring cold solution of 2 M aqueous HCl, and the pH was adjusted to 4. The resulting precipitate was filtered, washed with water and allowed to air dry before being suspended in i-PrOH. n-Bu 3 P (0.2 eq) was added and the mixture stirred at 80° C. for 1 h. After cooling to room temperature, the solid was filtered, washed with i-PrOH and dried to yield triazole 9 as solid.

         [0030]    General procedure for the preparation of amides (1): 
         [0031]    A suspension of carboxylic acid 9 (300 mg) in anhydrous acetonitrile (5 mL) containing DMF (1 drop) was cooled to 10° C. Oxalyl chloride (1.5 eq) and pyridine (1.2 eq) were added slowly. The reaction mixture was allowed to stir at room temperature for 1 h. After distillation under vacuum, the residue was dissolved in acetonitrile (5 mL), and treated with the desired amine (1.0 eq), DMAP (3 mol %) and pyridine (0.4 eq). The reaction was stirred at room temperature for 16 h. The mixture was dissolved in warm EtOAc, washed with 25% K 3 PO 4 , dried (MgSO 4 ) and concentrated. Purification using combiflash (3-5% MeOH in CH 2 Cl 2 ) afforded the desired amide.
