Sodium Sulfate → 2,2-Dimethyl-5-(sec-butylamino)-3-hexanone

Participants

Reaction Steps

To a solution of 5.00 g (35.16 mmol) 2,2-dimethyl-3,5-hexanedione in 20 mL of toluene loaded with 10.00 g of sodium sulfate was added 5.14 g (70.32 mmol) sec-butylamine. The mixture was refluxed 3 days. 4.90 g of light yellow oil was obtained after work-up. The isolated yield was 71%. 1H NMR (500 MHz, C6D6): δ=11.52 (s, 1H), 5.18 (s, 1H), 2.95 (m, 1H), 1.51 (s, 3H), 1.31 (s, 9H), 1.14 (s, 2H), 0.80 (d, 3H), 0.67 (t, 3H).
