実験手順
To a solution of 218 (363 mg, 0.96 mmol) in MeOH (6 mL) was added 4N HCl/dioxane (2.87 ml, 11.5 mmol) and the reaction was stirred at RT for 2 h then concentrated in vacuo to afford 394 g (100%) of 1-(4-chloro-1-(tetrahydro-2H-pyran-2-yl)-1H-benzo[d]imidazol-5-yl)-N-methylmethanamine (220) as its bis-HCl salt: MS (ESI) m/z=280.1 [M+1]+.
