Disclosed are methods for preparing 2-alkynyladenosine derivatives of formula A:
or a stereoisomer, pharmaceutically acceptable salt, hydrate, solvate, acid salt hydrate or isomorphic crystalline form thereof, the method comprising the step of:
contacting 2-iodoadenosine-5′-N-ethyluronamide with a compound of formula B:
wherein Z is —C(═O)OR or —CH
2
OC(═O)R, where R is a C
1
to C
5
alkyl, preferably methyl. The methods are useful for preparing 2-alkynyladenosine derivatives that are, in certain embodiments, adenosine receptor agonists.
本发明涉及制备2-炔基腺苷衍生物的方法,其化学式为A:或其立体异构体、药学上可接受的盐、水合物、溶剂合物、酸盐水合物或同晶形式,所述方法包括以下步骤:将2-碘腺苷-5'-N-乙基脲与化合物B的接触:其中Z为-C(=O)OR或-CH2OC(=O)R,其中R为C1至C5烷基,优选为甲基。该方法用于制备2-炔基腺苷衍生物,在某些实施例中,其为腺苷受体激动剂。
