The chlorine group (2e) further empowers the synthesis to a 38% yield. For the meta substitution, the electron-donating group can outperform the electronwithdrawing group. With a methyl substituent (2f), the reaction proceeds to a yield of 36%. For a methoxy group (2g), the reaction can reach the 37% yield. The yield declines to 33% when substituted with a chlorine group (2h) and descends down to 31% with a bromine group (2i). Gratifyingly, structural simplification to the completely unsubstituted amidine (2j, 46%) also presents a working substrate.
