(3-tert-butyl-1-(3-chlorophenyl)-1H-pyrazol-5-yl)methanamine → 1-((3-tert-butyl-1-(3-chlorophenyl)-1H-pyrazol-5-yl)methyl)-3-(4-(1,2,3-trihydroxypropan-2-yl)phenyl)urea

Participants

Reaction Steps

To a stirred MeCN (9 mL) solution of (3-tert-butyl-1-(3-chlorophenyl)-1H-pyrazol-5-yl)methanamine (102 mg, 0.387 mmol, 1.0 eq), TEA (0.214 mL, 1.55 mmol, 4.0 eq) followed by phenyl 4-(1,2,3-trihydroxypropan-2-yl)phenylcarbamate (119 mg, 0.395 mmol, 1.02 eq) was added at RT and the mixture was stirred for 16 h at reflux, then it was concentrated under vacuum and the residue purified by CC using EtOAc as eluent to get 1-((3-tert-butyl-1-(3-chlorophenyl)-1H-pyrazol-5-yl)methyl)-3-(4-(1,2,3-trihydroxypropan-2-yl)phenyl)urea (122 mg; 67%).
