Participants

Reaction Steps

N-(2,3-Dihydro-1,4-benzodioxin-6-yl)-4-methylbenzenecarboxamidine To a solution of 0.605 g (4.0 mmol) of 1,4-benzodioxan-6-amine in 5 mL of tetrahydrofuran at ambient temperature was added 2.2 ml (4.4 mmol) of 2.0 M (in tetrahydrofuran) sodium bis(trimethylsilyl)amide and the resulting solution was stirred for 20 min. To this reaction mixture was slowly added a solution of 0.47 g (4.0 mmol) of p-tolunitrile in 2 mL of tetrahydrofuran. The resulting mixture was stirred at ambient temperature for 5 hrs and then poured into brine (25 mL) and dichloromethane (50 mL). The organic layer was separated and the aqueous layer was extracted with 25 mL of dichloromethane (25 mL). The combined organic layers were dried over sodium sulfate, filtered and concentrated in vacuo to yield the title compound as brown crystalline solid, which was used without further purification. LC/MS 269.2 (M+1).
