Reaction Steps

To a solution of the compound obtained in Step A (57.83 mmoles) in acetonitrile (260 ml) there are added 1-bromomethyl-4-nitro-benzene (63.61 mmoles) and potassium carbonate (231.32 mmoles). The reaction mixture is stirred at 80° C. for 1 hour under nitrogen. The reaction mixture is brought to ambient temperature and 100 ml of water are added. Extraction with ethyl ether (3×350 ml) is carried out and the organic phases are combined. The organic phase obtained is dried over sodium sulphate, filtered and evaporated to dryness. The solid is triturated in ethyl ether, filtered off and dried in vacuo to yield the title product, which is used directly in the next Step.
