反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: In analogy to the procedure described for the synthesis of 5-tert-butyl-7-(3,3-difluoropyrrolidin-1-yl)-3-ethyl-3H-[1,2,3]triazolo[4,5-d]pyrimidine (example 61), the title compound was prepared from 5-tert-butyl-7-(3,3-difluoropyrrolidin-1-yl)-3H-[1,2,3]triazolo[4,5-d]pyrimidine and 1-(bromomethyl)-2-chloro-3-fluorobenzene and isolated as light-yellow gum. MS (m/e): 425.3 (MH+). isolated as light-yellow gum

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: A solution of 2-((3-fluorobenzyl)oxy)-7,8-dihydro-1,6-naphthyridin-5(6H)-one (20 mg, 0.05 mmol, prepared above as in Example 1.1) in DMSO (1 mL) was treated with 3-fluoro-2-chlorobenzyl bromide (20 mg 0.12 mmol) and KOtBu (20 mg, 0.18 mmol). The reaction mixture was stirred at RT overnight and then purified directly by RP-HPLC to give indicated compound. LC-MS (M+H)=415.3. purified directly by RP-HPLC to give
