Procedure

A mixture of ethyl 3-methoxy-4-[[2-[3-methoxy-4-[N′-(2-methylphenyl)ureido]phenylacetyl]-N-[2-cyclopropylamino]ethylamino]ethoxy]benzoate (195 mg, 0.30 mmol)) in THF:MeOH(4:1, v/v) (5 mL) and 1 N NaOH (0.756 mL) was stirred at 50° C. for 15 hr. The pH of the mixture was adjusted to 7.4 by the addition of 1 N HCl, and extracted with CHCl3:MeOH(9:1, v/v). The extract was washed with brine, dried over MgSO4, and evaporated in vacuo. The residue was crystallized with Et2O to give 57 mg (38%) 3-methoxy-4-[[2-[3-methoxy-4-[N′-(2-methyl phenyl)ureido]phenylacetyl]-[2-cyclopropylamino]ethylamino]ethoxy]benzoic acid 264 as a white crystalline material. mp 135–140° C.; IR (KBr), 3324, 2937, 1535, 1032, 754 cm−1; 1H-NMR (CD3OD, 400 MHz) δ 0.50–0.73 (m, 4H), 2.29 (s, 3H), 2.53 (m, 1H), 2.98 (m, 1H), 3.21 (m, 1H), 3.58–3.88 (m, 11H), 3.91 (s, 1H), 4.09 (m, 1H), 4.25 (m, 1H), 6.76–6.92 (m, 3H), 7.01 (m, 1H), 7.18 (m, 2H), 7.60 (m, 3H), 8.00 (d, J=8.3 Hz, 1H); MS (FAB) m/z 591(M+H)+; Anal.
