Procedure

0.08 ml of methyl iodide and then, at 0° C., 0.02 g of sodium hydride as a 60% suspension in oil are added to 0.2 g of the compound of Example 140 in 2 ml of tetrahydrofuran. After stirring for 16 hours at room temperature, the reaction mixture is hydrolysed with a 5% aqueous ammonium chloride solution and extraction is carried out with ethyl acetate. The organic phase is washed with water and dried over anhydrous sodium sulphate. The solvents are evaporated under reduced pressure. The product is obtained after crystallization from n-pentane; M.p.=122° C.
