合成路线1
该中间体在本合成路线中的序号:(XI)3) The title product labeled at 1, 2 and 4 positions is synthesized starting from [1,2,4-3H]-methylprednisolone and using the method described in the preceding paragraph to finally yield [1,2,4-3H]-methylprednisolone suleptanate. 4) The title product [14C]-labeled at the CO groups of the suberic acid is synthesized starting from methylprednisolone 21-O-mesylate (IX), which is condensed with [1,8-14C]-suberic acid (X) by means of diisopropyl ethylamine in DMF to yield the corresponding hemisuberate (XI). Finally, this compound is condensed with N-methyltaurine sodium salt (II) by means of isobutyl chloroformate as before.
