YieldReaction ConditionsOperation in experiment
69% To a solution of oxetan-3-ol (0.273 mL, 4.14 mmol) in dry DMF (5 mL) was added sodium hydride (60% in mineral oil, 265.5 mg, 5.53 mmol), and the mixture was stirred at r.t. for about 1 h. 5-(Chloromethyl)-l,3-dimethyl-lH-pyrazole (400 mg, 2.76 mmol) in DMF (5 mL) was added and the reaction mixture was stirred for 16 h at r.t. After removal of DMF under vacuum, the residue was dissolved in DCM (50 mL) and water (20 mL). The aqueous layer was extracted with DCM and the combined organic extracts were washed with brine, then dried over Na2S04 and evaporated to dryness. The crude residue was purified by column chromatography, with a gradient of 25-100%) EtOAc in heptane, to afford the title compound (349 mg, 69%).

YieldReaction ConditionsOperation in experiment
44% In toluene; for 12h;Reflux; Dean-Stark; To a solution of <strong>[32249-35-7]methyl 3-cyclopropyl-3-oxopropanoate</strong> (1 g, 7.03 mmol, 1.2 eq.) in toluene (5 ml) was added oxetan-3-ol (0.37 ml, 5.87 mmol, 1 eq). The resultant mixture was refluxed using a Dean-Stark trap for 12 hours, cooled to RT and concentrated. The resulting residue was purified by flash column chromatography on silica gel using ethyl acetate/hexane (1:3) as eluent to afford the title compound as a light-yellow oil (0.52 g, 44%). 1H-NMR (300 MHz, CDCl3) δ = 5.50 (p, J = 5.8 Hz, 1 H), 4.99-4.81 (m, 2H), 4.66 (dd, J = 7.8, 5.8 Hz, 2H), 3.63 (s, 2H), 2.02 (tt, J = 7.8, 4.5 Hz, 1 H), 1.17-1.08 (m, 2H), 1.05-0.93 (m, 2H).
