Participants

Reaction Steps

1-(3-Methoxy-2-methyl-4-pyridyl)piperazine (20.7 mg, 0.1 mmol) was dissolved in dichloromethane (1 ml), triethylamine was added (1 ml of a 0.12 M solution in dichloromethane) followed by a solution of (E)-4-methylpent-2-enoyl chloride (1 ml, 0.12 M in dichloromethane). The mixture was shaken briefly, washed with 5% sodium bicarbonate solution (2×), water and evaporated to dryness. The raw product was purified by preparative HPLC (gradient of water containing 0.1% ammonia and acetonitrile) to yield 2.2 mg of a solid (0.007 mmol, 7%).
