Procedure
To 3.30 g (8.70 mmol) tert-butyl 1-(4-((4-ethoxyphenyl)ethynyl)phenyl)propan-2-yl-carbamate (I60) in 40 mL MeOH are added 20 mL (25 mmol) HCl (1.25M in MeOH). The mixture is stirred at 70° C. for 7 h. The solvent is removed in vacuo and the crude product is triturated with DIPE and dried in normal atmosphere.
