Procedure

281 mg of the product obtained in Stage 1 of Example 7, 4 ml of methanol, 0.2 ml of 3,4-dichloro-benzaldehyde and 0.2 ml of acetic acid are mixed together and the reaction medium is agitated for 2 hours and 30 minutes, 0.1 g of NaBH3CN is added and agitation is carried out at ambient temperature for 1 hour. After evaporating the solvent, the residue is chromatographed on silica eluting with CH2Cl2/methanol/ammonium hydroxide (95/0.5/0.33) and 278.4 mg of expected product is obtained.
