Participants

Reaction Steps

Hex-5-en-2-one (9.8 g, 11.6 ml, 100 mmol) was added to a stirred solution of allylamine (8.55 mmol, 11.25 ml, 150 mmol), 4 Angstrom molecular sieves (52 g), and p-toluene sulfonic acid (10 mg) in CH2Cl2 (200 ml) and was stirred overnight. The reaction mixture was concentrated in vacuo by rotary evaporation and was used in the next reaction without further purification (13 g, 95%). Electrospray mass spec: M+H+=137.9
