N-Iodosuccinimide → 6-(4-fluoro-phenyl)-3-iodo-2-phenoxymethyl-7,8-dihydro-6H-imidazo[1,2-c]pyrimidin-5-one

Participants

Reaction Steps

N-iodosuccinimide (73.4 mg, 0.33 mmol) was added to a stirred solution of 6-(4-fluoro-phenyl)-2-phenoxymethyl-7,8-dihydro-6H-imidazo[1,2-c]pyrimidin-5-one (0.1 g, 0.3 mmol) in a mixture of ACN (2 mL) and acetic acid (2 mL). The mixture was stirred at RT for 3 days. The mixture was diluted with DCM and washed with a saturated solution of Na2CO3. The organic layer was separated, dried (Na2SO4), filtered and the solvents evaporated in vacuo. The crude product was triturated with MeOH to yield 6-(4-fluoro-phenyl)-3-iodo-2-phenoxymethyl-7,8-dihydro-6H-imidazo[1,2-c]pyrimidin-5-one (46 mg, 56% yield) as a brown solid, that was used in the next step without further purification.
