2-tert-Butyloxirane → HCID 86711759, compound

Participants

Reaction Conditions

Reaction Steps

A mixture of 2,4,6-trichloro-pyrimidin-5-ol (400 mg, 2.01 mmol) and 2-tert-butyl oxirane (3 mL) was heated at 100° C. for 3 hours before being cooled and concentrated in vacuo. The resultant residue was triturated in hot methanol and the insoluble material removed. The filtrate was concentrated in vacuo and the resultant residue was purified by column chromatography (SiO2, 0-15% ethyl acetate in cyclohexane) to give 3,3-Dimethyl-1-(2,4,6-trichloro-pyrimidin-5-yloxy)-butan-2-ol as a white solid (275 mg, 52%). 1H NMR (400 MHz, CDCl3): δ 4.28 (1H, dd, J=9.38, 2.19 Hz), 4.00 (1H, t, J=9.19 Hz), 3.76-3.69 (1H, m), 2.53 (1H, d, J=3.48 Hz), 0.95 (9H, s).
