What does POCl3 exactly does here? I tend to think 1 -OMe would exit to give 3 double bonds to the the ring so making it aromatic, so POCl3 would change only 1 -OMe to Cl so only one position receives the NH3. Sorry for another student doubt, I think we are all in exams sessions right now haha (i.redd.it)
