Reaktionsschritte

To a solution of N-methyl-2,4-dichloroaniline (0.133 g, 0.755 mmol) and triethylamine (0.105 mL, 0.755 mmol) in tetrahydrofuran (1.5 mL, 18 mmol) was added 4,5-dihydrobenzo[b]thieno[2,3-d]oxepine-2-carbonyl chloride (0.100 g, 0.378 mmol) portion wise as a solid. Reaction was stirred at room temperature with monitor for formation of desired product. The reaction was stirred overnight. After aqueous workup, the crude was taken into DMF at a concentrated of 100 mg/ml and purified by preparative RP-HPLC to give 108. Yield=30% of theoretical. MS: (ESI+) 405.5
