1-Bromo-2-Chloroethane → HCID 18184158, compound

Participants

Reaction Steps

4 g (19.4 mmol) of Methyl 4-tert-butylphenylacetate, 39 mg (1.0 m, 2 Eq.) of lithium bis(trimethylsilyl)amide, and 3 g (2 Eq.) of 1-bromo-2-chloroethane in 100 mL dry THF were reacted as described in Preparation 11, except that the reaction mixture was stirred for one hour at ambient temperature before work-up. This reaction yielded 4.21 g of a brown oil. This material was purified via silica gel chromatography eluting with a gradient solvent of hexane to hexane/EtOAc 19:1 to yield the title compound 1.57 g (35%) as a pale yellow solid m.p. 58°-60° C. Calculated for C15H20O2: Theory: C, 77.37; H, 8.81 Found: C, 77.54; H, 8.68.
