Diisopropylethylamine → 3-[4-(Azetidin-1-ylcarbonyl)-2-fluorophenoxy]-5-[(1S)-2-hydroxy-1-methylethoxy]-N-(1-methyl-1H-pyrazol-3-yl)benzamide

Participants

Reaction Steps

DIPEA (93 mg, 0.72 mmol; 4.0 equivalents) was added to a suspension of 3-[4-(azetidin-1-ylcarbonyl)-2-fluorophenoxy]-5-[(1S)-2-hydroxy-1-methylethoxy]benzoic acid (70 mg), HATU-(144 mmol; 2.1 equivalents) and 1-methyl-1-H-pyrazole-3-amine (26 mg, 0.27 mmol, 1.5 equivalents) in DMF (2 mL). The resulting mixture was stirred at ambient temperature for 16 hours. The DMF was removed in vacuo, water was added and the mixture extracted with ethyl acetate. The extracts were combined, washed with brine, dried (MgSO4), filtered, and evaporated in vacuo to give the crude product which was chromatographed, eluting with 0-100% ethyl acetate in isohexane, to give desired compound (45 mg).
