実験手順

To a solution of 1.00 g (8.62 mmol) of [1-(hydroxymethyl)cyclobutyl]methanol in 20 ml of (1:1) tetrahydrofuran:dimethylforamide was added a 60% dispersion of 0.413 g (8.62 mmol) of sodium hydride in oil. The reaction was stirred for 15 min and 1.28 g (8.62 mmol) of 2,4-dichloropyrimidine was added. After stirring for 2 h, the reaction was concentrated under vacuum and the residue was purified using silica gel chromatography eluting with ethyl acetate:hexane (4:6) to afford 0.9 g (51%) of (1-{[(2-chloro-4-pyrimidinyl)oxy]methyl}cyclobutyl)methanol as a colorless oil. 1H NMR (300 MHz, CDCl3) δ 8.32 (d, J=6 Hz, 1H), 6.69 (d, J=7 Hz, 1H), 4.51 (s, 2H), 3.67 (s, 2H), 2.35 (br s, 1H), 2.05-1.87 (m, 6H).
