Reaction Steps

250 ml of a 25%-strength aqueous ammonia solution was added to a solution of 35 g of the N-benzyl-2-(2,2-dimethyl-1a,7b-dihydro-2H-oxireno[c]chromen-6-yl)acetamide obtained above in 250 ml ethanol, and the mixture was stirred for 18 hours at room temperature. The reaction mixture was poured into 500 ml water and extracted with 250 ml dichloromethane. The organic phase was separated, dried over sodium sulfate and largely evaporated under reduced pressure. 200 ml diethyl ether was added to the remaining residue. The crystals produced after a while were removed by suction and dried on a rotary evaporator at 60° C. and 20 bar. 11 g 2-(4-amino-3-hydroxy-2,2-dimethyl-3,4-dihydro-2H-chromen-6-yl)-N-benzylacetamide was obtained as grey solid, which was used without further purification or characterization for the subsequent reaction.
