반응 단계
10 gms of p-tert-butyl-N-[6-chloro-5-(2-methoxy-phenoxy)-[2,2′-bipyrimidin]-4-yl]benzenesulfonamide potassium salt and calcium hydroxide (14.5 gms) were charged to a reaction vessel. Ethylene glycol (30 ml) and toluene (100 ml) were added to the vessel. The reaction mass was heated at a temperature of 100° C. for 5 hours or until the reaction was complete. The resulting suspension was cooled to 25° C., filtered and isolated as the calcium salt of bosentan.
