Participants

Reaction Steps

Add trifluoroacetic acid (1 mL) to a solution of tert-butyl {3-[2-(2,3-dihydro-1H-inden-2-ylamino)-7,8-dihydropyrido[4,3-d]pyrimidin-6(5H)-yl]-3-oxopropyl}carbamate (0.19 g; 1.0 equiv; 0.44 mmoles) in dichloromethane (1 mL) and stir for 16 hours. Concentrate the mixture and then partition the residue between dichloromethane and 1N sodium hydroxide. Separate the layers and further extract the aqueous layer with dichloromethane. Wash the combined organic extracts with brine, dry over sodium sulfate, filter, and concentrate to afford the desired 3-amino-1-[2-(2,3-dihydro-1H-inden-2-ylamino)-7,8-dihydropyrido[4,3-d]pyrimidin-6(5H)-yl]propan-1-one (0.145 g; 98%): MS (m/z): 338(M+1).
