Procedure
In a flask, methyl 3-(diphenylmethyleneamino)-1-(4-fluorobenzyl)cyclohexanecarboxylate (crude, from previous step) was dissolved in tetrahydrofuran (15 mL). Concentrated hydrochloric acid (1.2 mL) was added to the reaction. The reaction was stirred at room temperature for 5 hours. The resulting reaction mixture was concentrated to yield the crude product. The crude product was progressed to the next step without further purification.
