Reaction Steps

1-[tert-Butoxycarbonyl-(1-tert-butoxycarbonyl-5-methyl-1H-pyrazol-3-yl)-amino]-3-isopropyl-4-oxo-3,4-dihydro-phthalazine-6-carboxylic acid (13.0 mg, 0.02 mmol) was dissolved in a 20% TFA/DCM solution (2 ml) and the reaction mixture was stirred for 48 hours. After this time, the reaction mixture was concentrated and the resulting residue was triturated with diethyl ether to give the title compound (Example M-1) as a white solid. 1H-NMR: (400 MHz, D6- DMSO), 9.34(1H, s), 8.73 (1H, s), 8.47 (1H, d), 8.26 (1H, d), 6.28 (1H, s), 5.20-5.17 (1H, m), 2.19 (3H, s), 1.26 (6H, d) MS (ESI+)=(M+H)+ 328.31.
