Procedure
Sodium hydride (60% dispersion, 43 mg, 1.09 mmol) was added to a solution of N-hydroxy acetamidine (81 mg, 1.09 mmol) in THF (2 mL) and the resulting mixture was stirred at 50° C. for 15 minutes. Ethyl 9-[(4-chlorophenyl)sulfonyl]spiro[9-azabicyclo[3.3.1]nonane-3,2′-[1,3]dioxolane]-7-carboxylate (50) (0.394 g, 0.916 mmol) in THF (2 mL) was added to the reaction mixture and the resulting solution was stirred at room temperature for 1 hour. The mixture was diluted with EtOAc and washed with H2O. The organic phase was dried (Na2SO4), filtered and concentrated under vacuum to yield 0.40 g (quant.) of compound 51. MS (ESI) 440.1 (M+H).
