2,2,2-Trifluoroethanol → Methyl 3-(butylamino)butanoate

Participants

Reaction Steps

The reaction was carried out in a manner similar to that in Example 9, except that 26.2 mg (0.0292 mmol) of Ru(OCOCH3)2((S)-tol-binap), 500 mg (2.92 mmol) of methyl 3-(n-butylamino)crotonate and 2.5 ml of 10% hydrogen chloride-methanol solution were used instead of 78.0 mg (0.0869 mmol) of Ru(OCOCH3)2((S)-tol-binap), 1.00 g (8.69 mmol) of methyl 3-aminocrotonate and 5 ml of 2,2,2-trifluoroethanol, respectively, and except that the reaction was carried out for 16 hours instead of 15 hours, and the reaction mixture was treated as in Example 9 to give methyl 3-(n-butylamino)butanoate in a yield of 10.6%.
