Chloro(1 ,1-dimethylethyl)dimethylsilane (115g; 0.76mol) was added in portions over 1 hour to a solution of ethyl 4-hydroxycyclohexanecarboxylate (118g; 0.68mol), imidazole(103g; 1.52mol) and dimethylformamide (400ml) stirred under an atmosphere of argon. A small exotherm was observed resulting in the reaction mixture temperature increasing to~40C. The mixture was stirred at room temperature overnight then poured into 10% citric acid solution (2L) and extracted with diethyl ether (2 x 800ml). The ether extracts were washed with water, brine and then dried (Na2SO4) and the solvent was removed to give the title compound as a oil (198.4g) 1H NMR delta (CDCI3, 400 MHz): 0.01 (6H, m), 0.85 (9H, s), 1.2 (3H, m), 1.3-1.5 (2H, m), 1.6 (2H, m), 1.85-2 (3H, m), 2.15-2.3 (1 H, m) 3.5 (0.4H, m) 3.86 (1 H, m) 4.1 (1 H, m).

According to the analysis of related databases, 3618-04-0, the application of this compound in the production field has become more and more popular.
