trans-2-Phenylcyclopropyl isocyanate → (+/-)-trans-N-(4-(4-Ethylaminopyrimidin-6-yl-oxy)-phenyl)-N'-(2-phenyl-cyclopropyl)-urea

Participants

Reaction Steps

To a solution of 4-(4-ethylaminopyrimidin-6-yl-oxy)-aniline (Stage 89.1; 271 mg, 1.177 mmol) In THF (5 ml) under N2-atmosphere, trans-2-phenyl-cyclopropyl-isocyanate (188 mg, 1.18 mmol; Aldrich) Is added. Then the solution is stirred for 8 h, whereas a precipitate is formed. Filtration and washing with THF and ether yields the title compound: m.p.: 205-206° C.; 1H-NMR (DMSO-d6): 8.50 (s, HN), 8.11 (s, 1H), 7.42 (d, 2H), 7.27 (m, 3H), 7.15 (m, 3H), 7.01 (d, 2H), 6.67 (s, HN), 5.67 (s, 1H), 3.25 (m, 2H), 2.74 (m, 1H), 1.98 (m, 1H), 1.17 (m, 2H), 1.09 (t, 3H); Anal.: CHN.
