Методика

In a 20 mL scintillation vial equipped with a stir bar, 1-(2-chloro-5-(piperazin-1-ylmethyl)benzyl)-3-(6-methylpyridin-3-yl)urea hydrochloride salt (367 mg, 654 □mol) and DMAP (2 mg) were sealed with a septum cap and maintained under a positive nitrogen pressure. To the mixture was added 6 mL of anyhydrous CH2Cl2, followed by DIPEA (520 □L, 2.94 mmol) and methanesulfonyl chloride (70 □L, 785 □mol). The reaction mixture was stirred for 16 h. The reaction mixture was diluted with 6 mL of EtOAc. The organic solution was washed with 4 mL each of water and saturated NaCl solution, dried over Na2SO4, filtered and concentrated to afford 1-(2-chloro-5-((4-(methylsulfonyl)piperazin-1-yl)methyl)benzyl)-3-(6-methylpyridin-3-yl)urea as beige foam (209 mg).
