(3-tert-butyl-1-(3-chlorophenyl)-1H-pyrazol-5-yl)methanamine hydrochloride → 1-((3-tert-butyl-1-(3-chlorophenyl)-1H-pyrazol-5-yl)methyl)-3-(4-(3-hydroxyoxetan-3-yl)phenyl)urea

Reaction Steps

To a stirred solution of phenyl 4-(3-hydroxyoxetan-3-yl)phenylcarbamate (synthesis described for example A108) (97 mg, 0.34 mmol, 1.02 eq) and (3-tert-butyl-1-(3-chlorophenyl)-1H-pyrazol-5-yl)methanamine hydrochloride (100 mg, 0.33 mmol, 1.0 eq) in MeCN (8 mL) was added TEA (0.185 mL, 1.33 mmol, 4.0 eq) at RT and the mixture stirred at reflux overnight. The solvents were evaporated and the crude product was purified by CC (EtOAc/cyclohexane 3:2 as eluent) to get 1-((3-tert-butyl-1-(3-chlorophenyl)-1H-pyrazol-5-yl)methyl)-3-(4-(3-hydroxyoxetan-3-yl)phenyl)urea (92 mg; 61%).
