Reaction Steps

A solution of the crude 3-(2-tert-Butoxycarbonylamino-4-methyl-phenoxymethyl)-3,4-dihydro-2H-quinoline-1-carboxylic acid benzyl ester (crude, 0.35 mmol) in 4N HCl in dioxane (2 mL) at room temperature was stirred 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 corresponding to the crude aniline, which was used without purification in the urea forming reaction.
