Potassium → N-(3-Butoxy-2-oxo-1-sulfo-3-azetidinyl)-2-phenylacetamide, tetrabutylammonium salt

Participants

Reaction Steps

Following the procedure of Example 80, but substituting N-chloro-N-(2-oxo-1-sulfo-3-azetidinyl)-2-phenylacetamide, tetrabutylammonium salt (see Example 47A for preparation of the corresponding potassium salt) for 2-oxo-3-[N-chloro-N-[(phenylmethoxy)carbonyl]amino]-1-azetidinesulfonic acid, tetrabutylammonium salt, yields the title compound as an oil: nmr (CDCl3) 3.62 (s,2H,C6H5CH2), 4.03 (ABq,2H,ν=7 cps, C-4 CH2), 6.98 (s,1H,NH) and 7.30 ppm (S,5H,C6H5).
