Reaction Steps

A solution of 5-methyl-4-oxo-N-({3-[({[1-(triphenylmethyl)-1H-1,2,4-triazol-3-yl]carbonyl}amino)methyl]phenyl}methyl)-3,4-dihydrothieno[2,3-d]pyrimidine-2-carboxamide (565.0 mg, 0.849 mmol), triethylsilane (0.142 mL, 0.891 mmol) and trifluoroacetic acid (3 mL) in dichloromethane (10 mL) was stirred at room temperature for 30 min. The reaction mixture was concentrated under reduced pressure, and the residue was crystallized from IPE. The obtained powder was suspended in ethanol, and the suspension was stirred under heating for 2 hr to give the title compound as a white powder (359 mg, 99%).
