Reaction Steps
7-fluoro-3-[(trans-4-hydroxycyclohexyl)amino]isoquinoline-5-carboxylic acid (23.0 mg, 0.076 mmol) in 5 ml DMA was treated with HATU (62.1 mg, 0.16 mmol) and triethylamine (49.5 mg, 0.49 mmol). After 1 hour, 2-aminoethanol (15.0 mg, 0.25 mmol) was added and the solution was heated to 50° C. for 2 hours. The reaction was monitored by LC/MS to show no start acid left. The solvent was removed under vacuum and the crude was dissolved in CH2Cl2 and washed with 1 M NaHCO3 aqueous. The organic layers were dried over MgSO4. The crude material after removal of the solvent was purified by prepHPLC to give 5.8 mg (yield 19.3%). 1H NMR (400 MHz, MeOD) ppm 1.21-1.56 (m, 4H), 1.87-2.20 (m, 4H), 3.48-3.67 (m, 4H), 3.77 (m, 2H), 7.02 (s, 1H), 7.46-7.69 (m, 2H), 8.78 (s, 1H). HRMS: m/z 348.17226[M+H]+), calc. 348.17180. MS m/z, (APCI); 348.2 ([M+H]+).
