Participants

Reaction Steps

A solution of 1-(4-(4-chlorobenzyl)-2-(pyridin-4-yl)thiazol-5-yl)ethanone (370 mg, 1.12 mmol) in 1,1-dimethoxy-N,N-dimethylmethanamine (10.0 mL, 75.3 mmol) was heated to 80 degrees for 6 hours. The reaction was cooled and concentrated in vacuo. The residue was purified by silica gel chromatography (EA/DCM=0/100→100/0) to give 389 mg (90% yield) of the title compound as a yellow solid. LC/MS (FA) ES+ 384, 386. 1H NMR (300 MHz, CDCl3) δ: 8.70-8.68 (m, 2H), 7.81-7.75 (m, 3H), 7.36-7.33 (m, 2H), 7.26-7.24 (m, 2H), 5.41 (d, 1H, J=12.3 Hz), 4.55 (s, 2H), 3.16 (s, 3H), 2.88 (s, 3H).
