Procedure

3-Methylbutan-2-one (2.5 g, 1 eq.) and dimethylformamide diethylacetal (7.46 mL, 1.5 eq.) were heated at 100° C. for 4 days to give compound 232 as yellow viscous oil in 80% yield, which was used directly without further purification in the next step. 1H NMR (DMSO-d6, 400 MHz) δ (ppm) 0.94 (s, 3H), 0.95 (s, 3H), 2.52 (s, 1H), 2.74 (brs, 3H), 3.01 (brs, 3H), 4.96 (d, J=12.97 Hz, 1H), 7.45 (d, J=12.97 Hz, 1H).
