Reaction Steps

DIPEA (0.198 mL, 1.14 mmol) was added to a mixture of 3-[(2S)-1-(difluoromethoxy)propan-2-yl]oxy-5-phenylmethoxy-benzoic acid (0.10 g, 0.28 mmol), 1-methylpyrazol-3-amine (CAS no. 1904-31-0) (39 mg, 0.4 mmol) and HATU (0.227 g, 0.6 mmol) in DMF (3 mL) and stirred at RT for 20 hours. Ethyl acetate (30 mL) was added and the mixture washed with water (30 mL), brine (30 mL), dried (MgSO4), filtered and reduced in vacuo. The residue was chromatographed on silica, eluting with a gradient of 0-100% ethyl acetate in isohexane, to give the desired compound (0.1 g).
