To 0.86 g sodium methoxide in 15 ml methanol is added 1.6 g of N-[(4,6-dichloropyrimidin-2-yl)aminocarbonyl]-8-quinolinesulfonamide portionwise. This mixture is then heated to reflux temperature for 2 hours. The resultant white suspension is cooled to room temperature and filtered. The filtered white solid is dissolved up in a minimum amount of water and carefully acidified with 10% aqueous hydrochloric acid. The resultant white solid is filtered to give 0.65 g, m.p. 175°-177° C.
