6-Fluoro-1-(5-nitro-4-thiocyanatopyrimidin-2-yl)-1H-benzo[d]imidazole (498 mg, 1.57 mmol, 1.1 equiv) was added to a solution of (1R,4R)-4-(tert-butyldiphenylsilyloxy)-7-fluoro-1,2,3,4-tetrahydronaphthalen-1-amine (600 mg, 1.43 mmol, 1 equiv) in THF (20 mL) containing DIEA (1.5 mL), followed by adding 2 mL of DMSO. The resulted red solution was stirred at RT for 16 h. THF was evaporated off The residue was dissolved in EtOAc, washed with water and brine, dried (Na2SO4). The organic layer was evaporated to dryness. The residue was purified on ISCO (12 g column, MeOH—CH2Cl2 0-5%) to give a yellow solid product (633 mg, 65%). MS (ESI): 677.3.
