Sodium hydride → Trifluoroacetic acid

Participants

Reaction Steps

To a solution of NaH (38.3 mg, 0.956 mmol) in DMF (2 mL) was added (3,4,5-trifluorophenyl)methanol (65 mg, 0.401 mmol) at rt. The reaction mixture was stirred for 5 mins at rt, and then 8-chloro-1-methyl-3,4-dihydro-1H-pyrimido[1,6-a]pyrimidin-6(2H)-one trifluoroacetic acid salt (100 mg, 0.319 mmol) was added. The reaction mixture was stirred for another 1 h at rt, quenched with water and then filtered to give clear solution. The solution was purified by MDAP (0.3% TFA in water/MeCN) to afford the title compound as its TFA salt (16 mg, 0.036 mmol, 11.42%).
