Reaktionsschritte

Following a similar procedure to that described in reference example 7b, but starting fromethyl 4-nitrophenylacetate instead of ethyl diphenylacetate, and hydrolizing then the tert-butyl ester using p-toluenesulfonic acid in benzene at reflux instead of using trifluoroacetic acid, the title compound was obtained.
