Part-IIResults and DiscussionThe mass spectrum of compound Vxvii showed the molecular ion (M +. ) peak (a), m/e254, is corresponding to the molecular weight of the compound. The major mode offragmentation is loss of chloride ion from the molecular ion (a) to give daughter ion (b)m/e 219. The second daughter ion (c) m/e 239 was obtained by the loss of methyl radicalfrom the molecular ion (a). Alternatively, a neutral ethyl molecule is ejected out from themolecular ion to yield the fragment (d) m/e 225. This further loses CH 3 Cl as a neutralmolecule to afford fragment ion (e) at m/e 175. The fragmentation pattern of thecompound Vxvii is given in the Scheme 4.O+.ONHOO-Cl .Na, M+ = m/e 254Vxviia. - CH 3OClONHONH-CH 3 CH 3Ob, m/e 219NOONc, m/e 239ClO+.ONH- .
