Reaction Steps

2-Phenoxymethyl-6,7-dihydro-5H-pyrazolo[1,5-a]pyrazin-4-one (60 mg, 0.25 mmol) was added to a suspension of (rac)-(2-bromo-1-methyl-ethoxy)-tert-butyl-diphenyl-silane (0.23 g, 0.62 mmol) and 60% dispersion of sodium hydride in mineral oils (11 mg, 0.29 mmol) in THF (2 mL) at 0° C. The mixture was allowed to reach room temperature and stirred at 150° C. for 15 minutes under microwave irradiation. The mixture was used as such in the next step.
