✦ Synopsis

It can be seen from the mass spectrum of compound 2 that a, / 3 splitting also takes place but to a much lesser extent. The small peak at m / z 252 rel. int. 4% may be derived from the elimination of CH3CN from 6-azathymine prior to the splitting of the trimethylene chain. Also visible is the characteristic peak of the ion C,H,&O, at m / z 180, rel. int. 7%, which may be derived from the
