Reaction Steps

A cooled (0° C.) solution of N-(dibenzo[b,d]furan-2-ylmethyl)-2-methylpropane-2-sulfinamide (2.280 g; 7.55 mmol) in MeOH (24 ml) was treated dropwise with a solution of 4 M HCl in 1,4-dioxane (4.0 ml; 16.00 mmol). The resulting mixture was further stirred at 0° C., under nitrogen, for 10 min., and then at rt for 1 h. The reaction mixture was concentrated to dryness under reduced pressure. DCM, water, and Na2CO3 (5.50 g) were added, and the organic layer was then dried over anh. MgSO4, filtered, and concentrated to dryness under reduced pressure affording dibenzo[b,d]furan-2-ylmethanamine as a yellow solid. LC-MS (conditions A): tR=0.51 min.; no ionisation.
