Procedure

To a stirred solution of (3-tert-butyl-1-(3-chlorophenyl)-1H-pyrazol-5-yl)methanamine (80 mg, 0.31 mmol, 1.0 eq) in MeCN (7 mL) was added TEA (0.17 mL, 1.2 mmol, 4 eq) followed by phenyl 4-(1,3-dihydroxy-2-methylpropan-2-yl)phenylcarbamate (94 mg, 0.31 mmol, 1 eq) and the mixture was stirred for 16 h at reflux. The reaction mixture was concentrated under vacuum and the residue was purified by CC using EtOAc/n-hexane 1:1 as eluent to get 1-((3-tert-butyl-1-(3-chlorophenyl)-1H-pyrazol-5-yl)methyl)-3-(4-(1,3-dihydroxy-2-methylpropan-2-yl)phenyl)urea (106 mg; 73%).
