Participants

Reaction Steps

1,1'-Carbonyldiimidazole (1.17 g, 0.00722 mol) is added to a solution of {{5-[3,6-dihydro-3-methyl-2,6-dioxo-4-(trifluoromethyl)-1(2H)-pyrimidinyl]-1,2-benzisothiazol-3-yl}methoxy}acetic acid (1.50 g, 0.00361 mol) in tetrahydrofuran. The mixture is stirred one hour at reflux and cooled to room temperature. Methylsulfonamide (0.755 g, 0.00794 mol) is added, followed by 1,8-diazabicyclo[5.4.0]undec-7-ene (1.19 ml, 0.00794 mol). The resultant mixture is stirred overnight at room temperature, poured into 10% hydrochloric acid, and filtered. The resultant white solid is triturated in tetrahydrofuran, and filtered to give the title compound as an off-white solid (1.00 g, 56.2%, mp >240° C.) which is identified by NMR spectral analysis.
