Participants

Reaction Steps

Potassium carbonate (106 g) was added to 490 ml of an anhydrous DMF suspension of 120 g of the compound obtained in Step 1. After stirring for 2 hours, to the mixture was added 82.9 g of p-chlorobenzyl bromide at 0° C., and stirred for 3 hours at 0° C. and for 42 hours at room temperature. The reaction mixture was mixed with 500 ml of methanol and 450 ml of water, and stirred at 70° C. for 30 minutes. After cooling the mixture to room temperature, the precipitated crystals were suction filtered, rinsed with 50% methanol and water, and dried under reduced pressure, thereby yielding 102 g of transparent crystals of the desired compound (“Example Compound 23”).
