Reaction Steps

Synthesized according to general procedure 43. The reaction was set up with 4-iodo-N-(thiazol-2-yl)benzenesulfonamide (250 mg, 0.68 mmol), 1-(2,3-dihydro-1H-inden-2-yl)tetrahydropyrimidin-2(1H)-one (138 mg, 0.68 mmol), copper(I) iodide (267 mg, 1.4 mmol), potassium carbonate (282 mg, 2.0 mmol), and NMP (1.7 mL). The dark mixture was purified via silica gel chromatography using 10% MeOH in CH2Cl2 to obtain the desired urea as a white solid (45 mg, 0.10 mmol, 15% yield). 1H NMR (400 MHz, DMSO-d6) δ 12.71 (s, 1H), 7.71 (dd, J=1.9, 6.9 Hz, 2H), 7.45 (dd, J=1.9, 6.9 Hz, 2H), 7.26-7.21 (m, 3H), 7.23-7.11 (m, 2H), 6.83 (d, J=4.5 Hz, 1H), 5.25-5.19 (m, 1H), 3.68-3.65 (m, 2H), 3.20 (t, J=5.9 Hz, 2H), 3.09-2.98 (m, 4H), 2.01-1.91 (m, 2H). LC/MS (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA)), m/z: M+1 obs=455.3; tR=2.98 min.
