Reaction Steps

24.1 g of 3-[ 2-[4-(10,11-dihydro-2-nitro-dibenzo[b,f]thiepin-10-yl)-1-piperazinyl]-ethyl ]-2-oxazolidinone in 2000 ml of ethyl acetate are hydrogenated in the presence of 5.7 g of palladium/carbon (5%) at 70° C and 10 atmospheres of hydrogen. After filtration, the filtrate is concentrated under reduced pressure. There is obtained 3-[ 2-[4-(2-amino-10,11-dihydro-dibenzo[b,f]thiepin-10-yl)-1-piperazinyl]-ethyl ]-2-oxazolidinone which melts at 193°-196° C. After chromatographic purification over aluminium oxide using acetone/hexane as the elution agent, there is obtained a pure product which melts at 195.5°-196.5° C.
