Conditions: temp:110.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A solution of 30 g (219 mmol) N-methyl-p-anisidine was dissolved in 250 ml 62% aqueous HBr and 435 ml acetic acid. The reaction mixture was heated to 110° C. for 8 h, cooled and evaporated to yield 44.1 g (99%) of 4-Methylamino-phenol hydrobromide (1:1) as a brown solid, MS: 124 (MH+). cooled evaporated
