Procedure
158 mg (1.81 mmol) of morpholine are introduced into 10 ml of DMF at 0° C., and 367 mg (3.63 mmol) of triethylamine and a catalytic amount of potassium iodide are added. A solution of 300 mg of 7-chloro-2-(chloromethyl)-5-(methylthio)imidazo[1,2-c]pyrimidine (Example 26A) 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 221.8 mg (41% of theory) of product.
