Procedure

A solution of 0.420 g of the compound obtained in EXAMPLE 30 in 7 ml of DMF is cooled to 0° C. under an argon atmosphere and 0.027 g of sodium hydride as an 80% dispersion in oil is added. After stirring for 30 minutes, 0.05 ml of methyl iodide is added and the reaction mixture is stirred for 10 minutes. It is poured into water, extracted with AcOEt, washed with water, dried over sodium sulfate and evaporated under vacuum. The residue is chromatographed on silica using DCM and then a DCM/AcOEt mixture (95/5; v/v) as the eluent to give the expected product after crystallization from a DCM/iso ether mixture. m=0.211 g. M.p.=145°-148° C.
