PROCEDURE

实验过程

485 mg (0.64 mmol) of the compound from example 28A are introduced into dichloromethane (7 ml) at 0° C. 7 ml of a solution of 9 parts by volume of trifluoroacetic acid and 1 part of water are added and the reaction mixture is stirred for 45 min. The solvent is removed in vacuo and the residue is in each case taken up using dichloromethane and subsequently using toluene and concentrated to dryness. 588 mg of crude product are obtained, which is employed in the subsequent step without further purification.
