1) The iodination of 4-(1,2,4-triazol-1-ylmethyl)aniline (I) with ICl and CaCO3 in methanol/water gives the 2-iodoaniline (II), which is cyclized with 1-(triethylsilyl)-4-(triethylsilyloxy)-1-butyne (III) by means of paladium acetate and Na2CO3 in hot DMF yielding 5-(1,2,4-triazol-1-ylmethyl)-3-[2-(triethylsilyloxy)ethyl]-1H-indole (IV). The desilylation of (IV) with HCl in methanol affords the corresponding alcohol (V), which is condensed with dimethylamine by means of methanesulfonyl chloride and triethylamine to give MK-0462 free base (VI). Finally, this compound is treated with benzoic acid in isopropyl alcohol/isopropyl acetate solution.
