合成路线1
该中间体在本合成路线中的序号:(II)The title compound was prepared by several related methods. The sodium salt generated from tetraisopropyl methylenediphosphonate (I) and NaH was alkylated with 3,5-di-t-butyl-4-hydroxybenzyl chloride (II) in refluxing THF to afford the target arylethyl diphosphonate

合成路线2
该中间体在本合成路线中的序号:(II)In a related procedure, the dimethyl benzylamine (IV) was quaternized with iodomethane, and the resultant ammonium salt (V) was then condensed with the sodium salt of diphosphonate (I) (1). Other reported alkylating reagents included the bis-benzyl methyl amine (VII), prepared by Mannich reaction of methylamine with 2,6-di-t-butylphenol (VI) and formaldehyde, and the tris-benzyl amine (VIII), prepared by alkylation of ammonia with the benzyl chloride (II)

合成路线3
该中间体在本合成路线中的序号:(II)In a further method, condensation of benzyl alcohol (III) with methanol in the presence of a catalytic amount of HCl afforded the corresponding methyl ether (IX), which was then reacted with diphosphonate (I) in the presence of NaH to furnish the target arylethyl diphosphonate (1). Optionally, diphosphonate (I) was condensed with the benzyl acetate ester (X), prepared from benzyl chloride (II) and potassium acetate in acetone
