A mixture of tert-butyl-N-[1-oxo-1-[[1-(2-trimethylsilylethynyl)isoquinolin-3-yl]amino]-propan-2-yl]carbamate C4a (319 mg, 0.78 mmol), aqueous 1 N KOH solution (3 ml) and MeOH (10 ml) is stirred at RT for 2 h. The mixture is diluted with water and extracted with EtOAc. The combined organic layers are dried over Na2SO4 and concentrated in vacuo and the product purified by RP HPLC. Yield: 225 mg (86%). HPLC-MS: M+H=340; tR=1.84 min (*Method—1).
