UPLC traces of the NCL between 10 and 13 and isolation of 14. (A) NCL after 2 h. (B) Only 14 is obtained in the precipitate from H2O dilution after the NCL is complete (t = 6.5 h). (C) Only trace 14 remained in the supernatant after dilution of the NCL with H2O, while excess 10 remains entirely dissolved. *denotes absorption peak derived from MPAA.
