Procedure

The title compound was prepared according to the procedure of Example 367 C using (3-[5-(ethoxyiminomethyl)(1H-indazol-3-yl)]phenyl)-N-indan-2-ylcarboxamide.2HCl (360 mg, 0.72 mmol), N-amino-2-(dimethylamino) acetamide (254 mg, 2.17 mmol) and sodium methoxide (415 μL of a 25% w/w in methanol) in anhydrous methanol (4.0 mL) with a reaction time of 48 h. Purification of the residue by preparatory TLC using 50% ethyl acetate in methanol gave the desired product which was further purified by precipitation from methanol and ethyl acetate with hexanes and ethyl ether to give the title compound (86 mg, 25% yield) as a colorless powder 1H NMR (DMSO-d6) δ 13.9 (br s, 1H), 13.4 (br s, 1H), 8.85 (d, 1H), 8.6 (br s, 1H), 8.45 (s, 1H), 8.1-8.0 (m, 2H), 7.7-7.6 (m, 2H), 7.3-7.1 (m, 4H), 4.8-4.7 (m, 1H), 3.6 (br s, 2H), 3.25 (dd, 2H), 3.0 (dd, 2H), 2.2 (s, 6H); ES-MS (m/z) 478 [M+H]+.
