Reaction Steps

A mixture of 3-(4-Chloro-phenyl)-4-hydroxy-7-trimethylsilanylethynyl-isothiazolo[5,4-c]pyridine-5-carboxylic acid ethyl ester (51.5 mg, 0.119 mmol), glycine (269.7 mg, 3.59 mmol) and NaOMe (5.98 mL, 2.99 mmol, 0.5 M solution in MeOH) was refluxed for 24 h before it was concentrated in vacuo. The residue was dissolved in water (50 mL). The solution was then washed with CH2Cl2 (2×20 mL) before it was acidified by addition on aqueous 1N HCl solution. The resulting precipitate was sucked off, washed with water, and dried in vacuo to give the title compound (40 mg) as white solid: MS (m/z) 388.0 (M+1).
