[00479] To methyl 4-methyl-3-oxopentanoate (1.98 ml, 13.87 mmol) was added 1,1- dimethoxy-N,N-dimethylmethanamine (2.21 ml, 16.65 mmol) and the solution was stirred at 80 °C for 1 h. The reaction mixture was concentrated in vacuo to afford methyl-2- [(dimethylamino)methylidene]-4-methyl-3-oxopentanoate (2.76 g, 95%) as an orange oil. [00480] Method A: LC-MS m/z = 200.0 [M + H]+; RT = 1.00
