Reaction Steps

Cyclohexanecarbaldehyde (0.9 g, 5 mmol) was dissolved in 10 ml aqueous 1,4-dioxane, to which 200 mg (10 mmol) sodium borohydride was added. The reaction was run overnight at room temperature. After completion of the reaction, 5 ml 10% HCl solution was added and the product was extracted with ethyl acetate. The organic layer was separated and dried over sodium sulfate. The organic solvent was evaporated to give 0.8 g of 1-cyclohexyl-2,2,2-trifluoro-ethanol, yield 88%. NaH (80 mg, 60%, 3.0 mmol) was added to the solution of 1-cyclohexyl-2,2,2-trifluoro-ethanol (182 mg, 1 mmol) in 10 ml of anhydrous THF, the mixture was stirred for 20 minutes, 2-amino-4,6-dichloro-pyrimidine (164 mg, 1 mmol) was added and then the reaction mixture was heated at 70° C. for 1 hour. After cooling, 5 ml water was added and ethyl acetate (20 ml) was used to extract the product. The organic layer was dried over sodium sulfate. The solvent was removed by rotovap to give 202 mg of 4-chloro-6-[1-cyclohexyl-2,2,2-trifluoro-ethoxy]-pyrimidin-2-ylamine, yield 65%.
