Procedure

To a solution of piperonylamine (6.07 g, 38.95 mmol) and triethylamine (5.37 g, 53.12 mmol) in dichloromethane (100 ml) at 0° C. was added methanesulfonyl chloride (4.14 g, 35.41 mmol). The reaction was stirred at 0° C. for 1 hour. The mixture was then diluted with dichloromethane (100 ml) and washed with 1 N HCl (2×100 ml). The organic layer was dried (MgSO4), the solid was filtered and the filtrate was concentrated to give N-(3,4-methylenedioxy)benzyl-methanesulfonamide as a grey solid (8.4 g, 92% yield).
