A newdegradationproduct of spiradolinemesylate was recognized in aqueoussolution stored at 80 degrees C for 10 days. The structure of the degradationproduct was elucidated with spectroscopic data and a synthetic method as (1RS,3RS,8RS,10RS)-2-methyl-2,7-diazatricyclo - [6.4.0.0(3,7)]dodecane-10-spiro-2'-tetrahydrofurane by several two-dimensional NMR spectra. The fused imidazolidinering system
