The FT-IR spectrum of the compound showed a band at 1730 [cm.sup.-1] corresponding to carbonyl frequency and the absence of hydroxyl stretching band indicated the attachment of benzoyl group. In the [sup.1]H NMR spectrum, the presence of a three-proton multiplet at [delta] 7.25-7.53 and a two-proton multiplet at [delta] 7.82-8.22 were due to the benzoyl group.
In the second step, the coupling of metronidazole to the benzoyl group was accomplished in 10 h under reflux in DCM.
IDS-IS is chemically identical to IDS-P but is 5 Da heavier owing to the presence of 5 deuterium atoms in the benzoyl group. ESI-MS/MS detects and quantifies IDS-P and IDS-IS product ions after collision-induced elimination of S[O.sub.3] from the annhydromannosyl residue (80-Da mass difference; see Fig.
