Reaction Steps

3.051 g of 4-((2RS,4aRS,10bRS)-2-acetoxy-8,9-dimethoxy-1,2,3,4,4a,10b-hexahydro-phenanthridin-6-yl)-benzoic acid (compound B1), 3.00 g of S-methylisothiourea-sulfate and 10 mg of 4-dimethylaminopyridine are dissolved in 50 ml of acteonitril, than 1.80 g of 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride and 1, 23 ml of N-ethyl-diisopropylamin are added. After stirring for 16 hours the solvent is removed. The residue is dissolved in 20 ml of water and extracted with dichloromethane. After drying the combined organic layers with magnesium sulfate the solvent is removed to yield 3.652 g of the title compound as a yellow foam which is directly submitted to further reaction without purification.
