Procedure

To a solution of (9H-fluoren-9-yl)methyl hydroxycarbamate (5.20 g, 20.4 mmol) in ethyl acetate (300 mL) at −10° C. is added 4-chlorobenzoyl chloride (3.56 g, 20.3 mmol). Triethylamine (3 mL, 21.3 mmol) is added dropwise keeping the internal temperature below −5° C. After 10 min water (100 mL) is added and the separated aqueous layer is
