Participants

Reaction Steps

A mixture of tert-butyl-N-[1-[[5-(4,6-dimethylpyrimidin-5-yl)-6-(2-naphthalen-2-yl-ethynyl)pyridin-2-yl]amino]-1-oxopropan-2-yl]-N-methylcarbamate E2g (12 mg, 0.02 mmol) and DCM:TFA (9:1, 5 ml) is stirred at RT for 60 minutes. The mixture is diluted with toluene (10 ml) and concentrated in vacuo. The product is purified by RP HPLC. Yield: 6 mg (61%). HPLC-MS: M+H=436; tR=1.38 min (*Method—1).
