Procedure

A solution of [2-(1-Ethyl-1,2,3,4-tetrahydro-quinolin-3-ylmethoxy)-5-methyl-phenyl]-carbamic acid tert-butyl ester (40 mg, 0.1 mmol) was stirred in 4N HCl in dioxane (2 mL) at room temperature under a drying tube overnight. The suspension was concentrated by rotovap, diluted to 30 mL with CH2Cl2 and shaken with 10% Na2CO3 (30 mL). The organics were isolated, dried (MgSO4), filtered and concentrated to a brown oil, which was used without purification in the following reaction.
