Reaction Steps

N-benzyl-1-(6-chloro-3-iodo-1-trityl-1H-pyrazolo[4,3-c]pyridin-4-yl)propan-2-amine (670 mg, 0.958 mmol) and RuPhos pre-catalyst (70 mg, 0.096 mmol) were charged in a 2 dram vial, evacuated and backfilled with nitrogen and taken in toluene (4.8 mL). A solution of 2M NaOtBu in THF (1.2 ml, 2.4 mmol) was added and the reaction mixture was heated to 55° C. for 12 hours. The reaction mixture was cooled and diluted with EtOAc and washed with water, brine, dried with sodium sulfate and concentrated. Purification of the residue by flash column (0-50% EtOAc-hexanes) gave 7-chloro-3-(4-methoxybenzyl)-4-methyl-1,3,4,5-tetrahydropyrazolo[3,4,5-de][1,6]naphthyridine. MS ESI calc'd. for C35H30ClIN4 [M+H]+ 572. found 572.
