Procedure

8.85 mL (16.81 mmol) of phosgene solution (20 wt. % in toluene) is slowly added dropwise at 0° C. to a solution of 6.00 g (15.28 mmol) of tert-butyl{3-[2-(1-hydroxy-1-propylbutyl)phenylamino]-1,1-dimethylpropyl}carbamate and 5.32 mL (38.21 mmol) of triethylamine in absolute THF (80 mL). The mixture is stirred for 2 hours at RT, diluted with EtOAc, combined with ice, and made basic with saturated aqueous ammonia solution. The aqueous phase is exhaustively extracted with EtOAc and the combined organic phases are washed with saturated aqueous NaCl, dried with sodium sulfate, and evaporated down in vacuo. After column chromatography (silica gel, cyclohexane/EtOAc 6:1) the product is obtained as a yellow oil. Yield: 4.57 g (71%).
