To a solution of 4-(3-dimethylamino-propoxy)-3-(2-methyl-2H-pyrazol-3-yl)-phenylamine (20.5 mg, 0.075 mmol) in CH2Cl2 (2 mL) was added 4-chlorobenzyl isocyanate (0.17 μL, 0.128 mmol) and stirred overnight. The resulting material was purified by solid phase extraction (SCX, 1 gram cartridge), eluting with methanol (30 mL) followed by 2M NH3 in methanol (30 mL). The NH3 containing fractions were dried in vacuo to afford Compound 126 as a slightly yellow oil (29.8 mg, 90%).
