1-(Methylamino)adamantane → 3-(Difluoromethyl)-1-(5-fluoro-pyrimidin-2-yl)-1h-pyrazole-4-carboxylic acid (adamantan-1-ylmethyl)-amide

Participants

Reaction Steps

BOP (98 mg, 0.22 mmol) is added to a solution of 3-(difluoromethyl)-1-(5-fluoropyrimidin-2-yl)-1H-pyrazole-4-carboxylic acid (38 mg, 0.147 mmol), admantan-1-yl-methylamine (24 mg, 0.147 mmol) and DMA (0.052 mL) in DMF (1.0 mL) at rt. The mixture is stirred for 20 h. The mixture is poured into ice water (5 mL), extracted with EtOAc (3×20 mL) and dried over anhydrous MgSO4. The crude product is purified by silica gel column chromatography using 30% EtOAc/hexane to afford the title compound as a white solid. 1H NMR (DMSO-D6): 9.45 (s, 1H), 9.05 (s, 2H), 8.35 (m, 1H), 7.29-7.36 (t, 1H), 2.93 (d, 2H), 1.91 (m, 3H), 1.47-1.65 (m, 12H). MS (M+1)=406.28; RT=1.34 min *IC50.
