2-Bromopyrimidine → (R)-2-(3-methylpiperazin-1-yl)pyrimidine

Participants

Reaction Steps

To a solution of (R)-2-methyl piperazine (4.0 g, 40 mmol) in xylene (100 mL) at 140° C. under nitrogen was added 2-bromo pyrimidine (6.36 g, 40 mmol) slowly over a period of 30 min. The heating was continued for additional 15 h and cooled. The solid precipitate was filtered and dried under suction and neutralized with a saturated aqueous solution of sodium bicarbonate. The product was extracted with DCM (2×50 mL), dried and evaporated to afford the title compound as a liquid (2.4 g, 34%). TLC-Chloroform/MeOH (8/2); Rf: 0.2.
