From reaction between diethylketone and trimethylchlorosilane to form 3-trimethylsilyloxy-2-pentene(1.2.4.17). This product was reacted with 1-fluoropyridinium triflate(1.2.4.5) to obtain 2-fluoro-3-pentanone(1.2.4.9). After bromination with pyridinium bromide followed by reduction using diborane 2-fluoro-4-bromopentane-3-ol(1.2.4.18) was obtained. Reaction of this product with sodium methylate yielded the title compound (1.2.4.16). This compound was made also by reacting 2-(1-bromoethyl)-3-methyl oxirane(1.2.4.13) with HF/Py (70%) followed by treatment of the resulting 2-bromo-4-fluoropentan-3-ol(1.2.4.18) with K2CO3/MeOH.
