실험 절차

Chlorotrimethylsilane (0.30 mL, 2.41 mmol) was added to a solution of (S)-6-hydroxymethyl-2-phenoxymethyl-6,7-dihydro-5H-pyrazolo[1,5-a]pyrazin-4-one (0.33 g, 2.4 mmol) and TEA (0.33 mL, 2.4 mmol) in ACN (6 mL) at 0° C. The reaction was stirred for 30 minutes at room temperature. Then a 1N solution of HCl was added and the mixture extracted with AcOEt. The organic layer was separated, dried (Na2SO4), filtered and the solvent evaporated in vacuo to yield (S)-2-phenoxymethyl-6-trimethylsilanyloxymethyl-6,7-dihydro-5H-pyrazolo[1,5-a]pyrazin-4-one (0.375 g, 90% yield) as an off-white solid that was used in the next step without further purification.
