102 mg (1.17 mmol) of morpholine are introduced into 7 ml of DMF at 0° C., and 236 mg (0.78 mmol) of triethylamine and a catalytic amount of potassium iodide are added. A solution of 290 mg of 2-(chloromethyl)-7-(2,4-dichlorophenyl)-5-(ethylsulphanyl)imidazo[1,2-c]pyrimidine (Example 91A) in DMF is then slowly added dropwise. The mixture is allowed to reach RT and is stirred at this temperature for a further 16 h. Purification of the crude product by preparative HPLC and drying under high vacuum result in 214 mg (43% of theory) of product.
