Procedure

A solution of ethyl isocyanate (18.8 mg, 0.25 mmol) in MeCN (2 mL) was added, together with K2CO3 (34.5 mg, 0.25 mmol), to a solution of 4-[1 -(3,4-dimethoxyphenoxy)-4-(9-oxa-3,7-diazabicyclo[3.3.1]non-3-yl)-butyl]benzonitrile (Preparation H; 109.4 mg, 0.25 mmol) in chloroform (0.5 mL). The reaction mixture was stirred at rt for 4 days before being added to a solid phase extraction plug (SiO2, 0.5 g). The plug was washed with CHCl3:MeCN (2.5 mL of 80:20), and the product was finally eluted with CHCl3:MeOH (3×2.5 mL of 95:5) to give the title compound.
