Procedure

A stirred, cooled (ice bath) solution of 5-(cyclopropyl-methyl-amino)-8,8-dimethyl-5,6,7,8-tetrahydronaphthalene-2-carboxylic acid (Intermediate 56, 0.22 g, 0.83 mmol) in anhydrous tetrahydrofuran (4 mL) was treated with triethyl amine (0.16 mL, 1.1 mmol) followed by ethyl chloroformate (0.10 mL, 1.08 mmol). After 5 h, sodium azide (0.081 g, 1.24 mmol) was added and the reaction mixture was allowed to warm to ambient temperature and stirred overnight. The reaction mixture was diluted with water and extracted with ethyl acetate. The organic phase was washed with water and brine, dried over anhydrous sodium sulfate, filtered and evaporated in vacuo to afford the title product that was used as such for the next reaction (0.24 g, 98%).
