Versuchsvorschrift

ethyl 2-(3-amino-1,1-dioxo-thietan-3-yl)acetate (example 160c, 548 mg, 2.64 mmole) was dissolved in a solution 2.0M of methylamine in methanol (19.8 mL, 39.7 mmole) and the reaction mixture was stirred at 45° C. overnight. Removal of volatiles in vacuo yielded the title compound (505 mg, 99%) as crude light brown oil which was used without any further purification; MS (ESI, m/z): 193.1 (M+H+).
