Reaction Steps

A solution of 5-chloro-N-((1S)-2-(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)-1-{[2-(trifluoromethyl)phenyl]methyl}ethyl)-4-(1-methyl-1H-1,2,3-triazol-5-yl)-2-thiophenecarboxamide (700 mg, 1.22 mmol) and hydrazine (0.19 mL, 6.1 mmol) in 5 mL of MeOH was stirred at rt overnight, diluted with 200 ml of H2O and extracted with DCM (100 ml×2). The combined organic layers were concentrated and the resulting solid was dissolved in 6N HCl (50 ml). The aqueous layer was washed with DCM (50 ml×2). The organic layers were discarded and the remaining aqueous solution was concentrated to give the product as an HCl salt (490 mg, 75%): LCMS (ES) m/z 444.0 (M+H)+, 1H NMR (400 MHz, METHANOL-d4) ppm 8.10 (m, 1H), 7.92 (m, 1H), 7.73 (m, 1H), 7.57 (m, 1H), 7.44 (m, 1H), 4.65 (m, 1H), 4.17 (s, 3H), 3.25-3.11 (m, 4H).
