A simple, mild, and efficient one-pot method for the synthesis of substituted 2-aminothiazoles has been reported. The reaction involves the formation of sulfenyl bromide as an umpolung intermediate of nucleophilic sulfur, which is responsible for C-S bond formation leading to oxidative cyclization of ketones and thioureas to furnish the desired products. Carbon tetrabromide was used as a convenient and mild brominating reagent under basic condition at room temperature to give 2-aminothiazoles in good to excellent yields.

Compounds of Formula (I) wherein: R1 is hydroxymethyl; R2 is selected from -C(O)NR4R5, SO2NR4R5, S(O)pR4 and HET-2; HET-1 is a 5- or 6-membered, optionally substituted C-linked heteroaryl ring; HET-2 is a 4-, 5- or 6-membered, C- or N-linked optionally substituted heterocyclyl ring; R3 is selected from halo, fluoromethyl, difluoromethyl, trifluoromethyl, methyl, methoxy and cyano; R4 is selected from for example hydrogen, optionally substituted (1-4C)alkyl and HET-2; R5 is hydrogen or (1-4C)alkyl; or R4 and R5 together with the nitrogen atom to which they are attached may form a heterocyclyl ring system as defined by HET-3; HET-3 is for example an optionally substituted N-linked, 4, 5 or 6 membered, saturated or partially unsaturated heterocyclyl ring; p is (independently at each occurrence) 0, 1 or 2; m is 0 or 1; n is 0, 1 or 2; provided that when m is 0, then n is 1 or 2; or a salt, pro drug or solvate thereof, are described. Their use as GLK activators, pharmaceutical compositions containing them, and processes for their preparation are also described.
