Reaction Steps

An isopropanolic solution of i-PrONa, obtained by dissolving of sodium (0.017 g, 0.75 mmol, 2 equiv) in i-PrOH (2 ml), was treated with methyl [(4Z)-4-[1-(benzylamino)-2-morpholin-4-ylethylidene]-1-(2-chlorophenyl)-5-oxo-4,5-dihydro-1H-pyrazol-3-yl]acetate (Compound of Formula (XIV) (170 mg, 0.75 mmol, 1 equiv.). The reaction mixture was stirred at room temperature for 0.5 h, then cooled and neutralized to pH 6 by addition 1M HCl solution. i-PrOH were removed in vacuo and the crude was purified by flash chromatography to yield 9 mg of pure product 5-benzyl-2-(2-chlorophenyl)-4-(morpholin-4-ylmethyl)-1H-pyrazolo[4,3-c]pyridine-3,6(2H,5H)-dione. Yield 12%. 1HNMR (500 MHz, DMSO-d6): 2.37-2.41 (m, 4H); 3.94-4.00 (m, 2H); 5.52-5.55 (m, 2H), 5.84 (s, 1H); 7.07-7.09 (m, 2H), 7.22-7.28 (m, 2H); 7.30-7.33 (m, 2H); 7.48-7.51 (m, 2H); 7.59-7.61 (m, 1H); 7.63-7.67 (m, 1H). MS (ESI+): 451.9; MS (ESI−): 449.7.
