Participants

Reaction Steps

Prepared from methyl 3-methoxy-2,2-dimethylpropanoate (8 g, 54.7 mmol) according to the method described in Example 122A Step 1 for 4-methyl-3-oxopentanenitrile. Purification via silica gel chromatography eluting with mixtures of petroleum ether and ethyl acetate afforded 5-methoxy-4,4-dimethyl-3-oxopentanenitrile as a yellow oil (2.5 g, 29%). 1H NMR (300 MHz, CDCl3) δ 3.72 (s, 2H), 3.32-3.33 (m, 5H), 1.18 (s, 6H).
