A solution of 2-butyl-2-[3-chloro-4-(1,1,1,3,3,3-hexamethyl-disilazan-2-yl)-benzoyl]-pyrrolidine-1-carboxylic acid tert-butyl ester (0.205 g, 0.391 mmol) in methanolic 1N HCl (7.8 mL) was stirred at 50° C. under nitrogen for 2 hours. The reaction mixture was concentrated in vacuo to yield (4-amino-3-chloro-phenyl)-(2-butyl-pyrrolidin-2-yl)-methanone (0.249 g, quantitative yield) as a light brown powder and as a monohydrochloride salt.
