Reaction Conditions

Reaction Steps

Concentrated HCl was added to a cooled (0-5° C.) solution of isoamyl nitrite (14.0 g, 0.12 mol) and 1-ethoxy-3-methyl-2-butene (6.84 g, 0.06 mol). The temperature was maintained below 5° C. during the additiona and the reaction mixture was stirred at 5° C. for an additional 30 min. The product was filtered and washed with a cold (−20° C.) 1:1 mixture of ethanol and ether. The solid was further washed with ether to afford the title product as a white solid. Yield 6. g (64%). mp: 84-85° C. 1H NMR (CDCl3) δ1.12(t, 3H, CH2CH3), 1.65 (d, 6H, CH3), 3.49 and 3.95 (m, 2H, CH2OCH2CH3), 4.15 (m, 2H, CH2CH3), 6.12 (dd, 1H, [CH3]2 C=CH-). MS: 180 (M+H)+.
