Procedure

A mixture of 2-(5-(azetidin-3-ylsulfonyl)-2-neopentyl-1H-benzo[d]imidazol-1-yl)-N,N-dimethylethanamine (prepared in STEP A of Example 22, 554 mg, 1.46 mmol), triethylamine (226 microL, 1.61 mmol) and 2-chloroethanol (3.53 g, 43.9 mmol) was stirred at 60° C. for 9 h. The resulting mixture was diluted with water (30 mL) and extracted with dichloromethane (50 mL×3). The organic layer was dried over sodium sulfate and concentrated in vacuo. The crude product was purified by reverse phase HPLC (0.4% aqueous ammonia-acetonitrile=96:4 to 4:96) to give the title compound (238 mg, 39%) as a clear grease.
