YieldReaction ConditionsOperation in experiment
85% With N-ethyl-N,N-diisopropylamine; In 1,2-dichloro-ethane; at 100℃; for 6.0h; a) 2-Aminomethylene-malonic acid diethyl ester (16.7 g, 89.2 mmol) and 4- fluorophenyl isocyanate (10.6 mL, 93.7 mmol) in 1 ,2-dichloroethane (25 mL, 320 mmol) was added N,N-diisopropylethylamine (17.1 mL, 98.1 mmol) and heated at 100 C for 6h. The mixture was cooled on an ice bath and the solid collected and washed with ether to give the urea (24.5 g, 85%). mp = 198-200 C; LCMS m/z = 347 (M + 23); 1H NMR (DMSO) ?: 10.57 (d, 1H, J = 12.3 Hz), 10.41 (s, 1H), J = 12.45 Hz), 8.45 (d, 1H, J = 12.5 Hz), 7.48-7.53 (m, 2H), 7.16-7.21 (m, 2H), 4.24 (q, 2H, J = 7 Hz), 4.15 (q, 2H, J = 7 Hz), 1.22-1.28 (m, 6H).

1.01 g With N-ethyl-N,N-diisopropylamine; In 1,2-dichloro-ethane; at 100℃; for 16.0h; Diethyl 2-(aminomethylene)malonate (1.5 g, 8.0 . mmol, CombiBlocks) and 1- fluoro-4-isocyanatobenzene (0.957 ml, 8.41 mmol) were suspended in DCE (2.67 ml) at room temperature. DIPEA (1.539 ml, 8.81 mmol) was added followed by the dropwise addition of l-fluoro-4-isocyanatobenzene (0.957 ml, 8.41 mmol). The reaction mixture was heated to 100 C and stirred for 16 hr. The partially solidified reaction mixture was cooled to room temperature and diluted with 10 mL of 50% Et20-CH2Cl2. The remaining precipitate was filtered to afford diethyl 2-((3-(4-fluorophenyl)ureido) methylenelma.onate as a cream solid (1.01 g) 1H NMR (400 MHz, DMSO-d6) d 10.72 - 10.32 (m, 21 .}. 8 47 (br d,.1 5.7 Hz, 1H), 7.61 - 7.43 (m, 2H), 7.26 - 6 99 (m, 2H), 4.24 (q, 1=7.1Hz, 21 i s. 4.15 (q, 1=7.1Hz, 2H), 1.26 (dt, j 12.0. 7.1Hz, 6H); LC/MS (M+H) 325.2; LC RT = 0.92 min (Column: BEH C18 2.1 x 50mm; Mobile Phase A: water with 0.05% TEA; Mobile Phase B: acetonitrile with 0.05% TFA; Temperature: 50 C; Gradient: 2-98% B over 1.7 min; Flow: 0.8 mL/min)
