Triethylamine → {(R)-3-[3-(4-chloro-phenoxy)-azetidin-1-yl]-1-methyl-propyl}-carbamic acid tert-butyl ester

Participants

Reaction Steps

A solution of ((R)-3-iodo-1-methyl-propyl)-carbamic acid tert-butyl ester (0.038 mg, 0.13 mmol), 3-(4-chloro-phenoxy)-azetidine hydrochloride (0.030 g, 0.13 mmol) and triethylamine (0.073 ml, 0.52 mmol) in DMF (1 ml) is stirred at room temperature for 18 hours. The reaction mixture is partitioned between ethylacetate and a saturated solution of sodium bicarbonate. The organic phase is washed with water and brine, dried over magnesium sulphate and evaporated. The crude product is purified by flash silica chromatography using 1:1 ethylacetate:hexane as eluent to afford {(R)-3-[3-(4-chloro-phenoxy)-azetidin-1-yl]-1-methyl-propyl}-carbamic acid tert-butyl ester.
