N-(3-tert-Butyl-5-isoxazolyl)-N’-(4-phenoxyphenyl)urea: To a solution of 5-amino-3-tert-butylisoxazole (8.93 g, 63.7 mmol, 1 eq.) in CH2Cl2 (60 mL) was added 4-phenyloxyphenyl isocyanate (15.47 g, 73.3 mmol, 1.15 eq.) dropwise. The mixture was heated at the reflux temp. for 2 days, eventually adding additional CH2Cl2 (80 mL). The resulting mixture was poured into water (500 mL) and extracted with Et2O (3.x.200 mL). The organic layer was dried (MgSO4) then concentrated under reduced pressure. The residue was recrystallized (EtOAc) to give the desired product (15.7 g, 70percent): mp 182-184¡ã C.; TLC (5percent acetone/95percent acetone) Rf 0.27; 1H-NMR (DMSO-d6) delta 1.23 (s, 9H), 6.02 (s, 1H), 6.97 (dd, J=0.2, 8.8 Hz, 2H), 6.93 (d, J=8.8 Hz, 2H), 7.08 (t, J=7.4 Hz, 1H), 7.34 (m, 2H), 7.45 (dd, J=2.2, 6.6 Hz, 2H), 8.80 (s, 1H), 10.04 (s, 1H); FAB-MS m/z (rel abundance) 352 ((M+H)+, 70percent).
As the paragraph descriping shows that 59669-59-9 is playing an increasingly important role.
