Reaction Steps

N-Methyl-N-((1R)-1-(N-methyl-N-((1R)-1-(methylcarbamoyl)-2-(thiophen-2-yl)ethyl) carbamoyl)-2-(2-naphthyl)ethyl) carbamic acid tert butylester (1.38 g; 2.71 mmol) was dissolved in methylene chloride (6 ml) and triflouroacetic acid (4 ml) was added. The reaction mixture was stirred for 1 hour at room temperature. Water (30 ml) and solid sodium hydrogencarbonate were added to pH 8. The phases were separated and the aqueous phase was extracted with methylene chloride (4×20 ml). The organic phase was dried over magnesium sulfate and the solvent was removed over vacuo to afford 1.06 g of (2R)-N-methyl-2-methylamino-N-((1R)-1-(methylcarbamoyl)-2-(thiophen-2-yl)ethyl)-3-(2-naphthyl)propionamide.
