Procedure

To a slurry of trans-(7-carbamoyl-3-methoxy-1,1-dimethyl-1,2,3,4-tetrahydro-naphthalen-2-yl)-carbamic acid tert-butyl ester (9.22 g, 26.4 mmol) in DCM (100 mL) was added 4 N HCl in dioxane (25 mL, 100 mmol) slowly. The reaction mixture was stirred at RT for 15 h, concentrated to dryness, triturated with DCM (25 mL) for 30 min, filtered, rinsed with DCM (3×15 mL), and dried under vacuum. Ethanol (100 mL) was added and the reaction mixture was concentrated under vacuum to give the HCl salt of the title compound (7.17 g) as a white powder.
