The synthesis of [14C]-SCH-56592 has been described: The cyclization of semicarbazide (I) with [14C]-formamidine (II) in hot 2-methoxyethanol gives the triazolone (III), which is condensed with the sulfonate (IV) by means of Cs2CO3 in hot DMF to yield the alkylated triazolone (V). Finally, this compound is deprotected by hydrogenation with formic acid over Pd/C in hot methanol to afford labeled SCH-56592.
