In a variation of this procedure, aryl tetrazole (II) was alkylated with ICH3 to provide methyltetrazole (XV). Condensation of (XV) with tert-butyl carbazate afforded hydrazone (XVI), which was reduced to the benzylhydrazine (XVII) by means of NaBH3CN and p-toluenesulfonic acid. Opening of the Boc-protected epoxide (XVIII) with hydrazine (XVII) gave hydrazinoalcohol (XIX). Acid deprotection of both Boc groups of (XIX) furnished diamino compound (XX), which was finally coupled with N-methoxycarbonyl-L-tert-leucine (X) by means of TPTU.
