Reaction Steps

A mixture of 2-(difluoromethyl)thiazolo[5,4-d]pyrimidin-7-ol, N,N-dimethylaniline (0.800 mL, 6.31 mmol) and phosphorus oxychloride (6.00 mL, 65.5 mmol) in toluene (20 mL) was heated at 80° C. for 6 h. The reaction mixture was cooled of rt and the solvent removed invacuo. The residue was dissolved in DCM, evaporated onto silica gel and purified by flash chromatography (Isco (80 gram)) eluting with (EtOAc):hexanes (0:1→1:3) to give an off-white crystalline solid (252 mg, 18% over 2 steps). MS m/z=221.9, 223.9 [M+H]+. Calculated for C6H2F2N3S: 221.
