(11) The byproduct o-aminophenol 4 was likely formed by the
reduction of the intermediate A or C by pyrrolidine in the reaction
mixture.
(12) Piperidine could react with 1 but the reaction mainly gave o-
aminophenol type product (formed in a similar way as o-aminophenol
4) and it could not be converted to the corresponding N,O-acetal using
the method described in ref 10c.
