Reaction Steps

To a solution of (R)-2-amino-1-(4-(4-chlorophenyl)-3,3-dimethylpiperazin-1-yl)-3-methylbutan-1-one, TFA (30 mg, 0.07 mmol) and DIPEA (0.14 mmol) in CH2Cl2 (1 mL), was added 2-isocyanatopropane (7.00 mg, 0.08 mmol). The mixture was stirred at rt for 2 h and concentrated. The residue was purified by preparative HPLC to afford (R)-1-(1-(4-(4-chlorophenyl)-3,3-dimethylpiperazin-1-yl)-3-methyl-1-oxobutan-2-yl)-3-isopropylurea (11 mg, TFA salt) as a white solid. MS found 409.15 (M+H)+.
