A scale-up synthesis of isostericphosphonateanalog of mannose-6-phosphate (M6P) is presented via regioselective nucleophilic displacement of the protected 4,6-cyclic sulfate precursor by dialkyl lithiomethylphosphonates in the key step. The five-step synthesis requires only simple purification procedures after each step excluding chromatography separations. The usage of proper nucleophiles makes
