Reaction Steps

Tetraethyl3-nitronaphthalene-1,5-diphosphonate (4.00 g, 9.0 mmol) dissolved in methanol (150 ml) and 1N HCl aqueous solution (10 ml) was stirred with H2 and 5% Pd/C in PARR apparatus until H2 absorption ceased. After catalyst filtration on filter aid, the methanol was evaporated under reduced pressure; the residue was stirred with ethanol (10 ml) and diethyl ether (50 ml) and the separated crystalline solid was filtered, washed and dried to yield the title product isolated as the hydrochloride hemihydrate (3.78 g, decomp. 230°-240° C., 91%).
