1-Ethyl-3-(3'-dimethylaminopropyl)carbodiimide → HCID 68512052, compound

Participants

Reaction Steps

A solution of 3-(1-(4-methoxybenzyl)-4-(4-amino-2-fluorophenoxy)-1H-pyrazolo[3,4-b]pyridin-3-ylamino)cyclohexanol (50 mg, 0.10 mmol), 2-(4-fluorophenyl)-3-oxo-2,3-dihydropyridazine-4-carboxylic acid (74 mg, 0.31 mmol, obtained from Example 19 Step C), EDCI (120 mg, 0.63 mmol), Et3N (0.1 mL) and HOBT-H2O (96 mg, 0.63 mmol) was stirred in DMF (1 mL) for 10 hours. The reaction mixture was poured into water and extracted with CH2Cl2. The organic layer washed with saturated aqueous NaHCO3, 10% aqueous LiCl, dried with Na2SO4, filtered and concentrated. The residue was purified with flash silica gel chromatography (5% MeOH in CH2Cl2) to afford the product (35 mg, 48% yield) as a brown solid. LRMS (APCI pos) m/e 694.2 (M+H).
