Procedure
To a cooled (0° C.), stirred mixture of 1-(2-hydroxyethyl)-2-methylamino-1H-benzimidazole (8.05 g, 42.12 mmol), Et3N (4.26 g, 42.12 mmol), and CH2Cl2 (85 mL) was added a solution of MsCl (4.83 g, 42.12 mmol) in CH2Cl2 (10 mL). After 2 hours, H2O was added and the layers were separated. The aqueous phase was extracted with CH2Cl2. The combined extracts were washed with brine, dried, and concentrated to give 8.00 g (71%) of a white solid m.p. 48°-50° C.
