Reaction Steps

A solution of 955 mg (3.86 mmol) of methyl 4-(aminothioxomethyl)-5-methylthiothiophene-2-carboxylate (Maybridge, Cornwall, UK) was reacted with 1 g (3.86 mmol) of 1-[5-(tert-butyl)-2-methyl(3-furyl)]-2-bromoethan-1-one (1 g) in a manner similar to Example 8, step (a) to give methyl 4-{4-[5-(tert-butyl)-2-methyl(3-furyl)](1,3-thiazol-2-yl)}-5-methylthiothiophene-2-carboxylate (999 mg, 64%) as a red-brown solid. 1H-NMR (DMSO-d6; 300 MHz) δ8.14 (s, 1H), 7.74 (s, 1H), 6.46 (s, 1H), 3.86 (s, 3H), 2.74 (s, 3H), 2.66 (s, 3H), 1.27 (s, 9H). Mass spectrum (MALDI-TOF, CHCA matrix, m/z): Calcd. for C19H21NO3S3, 408.1 (M+H), found 408.0.
