Temperature: 100 °C

Procedure

A mixture of 4-chloro-2-(methylthio)pyrimidine-5-carbonitrile (2.15 g, 11.6 mmol)), (1S,4R)-4-amino-2,2-dimethylcyclohexanol (1.51 g, 10.5 mmol) and DIEA (2.72 mg, 21.1 mmol) in isopropanol (30 mL) was heated at 100° C. for 3 h. After removal of the organic solvent under reduced pressure, the residue was treated with water and extracted with ethyl acetate. The combined organic layers were washed with brine, dried over sodium sulfate and concentrated to give the crude product, which was purified by silica gel column chromatography (15% ethyl acetate in petroleum) to afford the title compound as a pale yellow solid (2.2 g, 7.53 mmol, 72% yield). MS (ESI) m/z 293.2 [M+H]+.
