To a stirred solution of (3-tert-butyl-1-(3-chlorophenyl)-1H-pyrazol-5-yl)methanamine (synthesis described for example A153) (102 mg, 0.387 mmol, 1.0 eq) in MeCN (9 mL) was added TEA (0.2145 mL, 1.55 mmol, 4.0 eq) followed by phenyl 4-(1,3-dihydroxypropan-2-yl)-3-fluorophenylcarbamate (120 mg, 0.395 mmol, 1.02 eq) at RT and the mixture was stirred at reflux for 16 h. The solvent was evaporated and the crude product was purified by CC using EtOAc as eluent to get 1-((3-tert-butyl-1-(3-chlorophenyl)-1H-pyrazol-5-yl)methyl)-3-(4-(1,3-dihydroxypropan-2-yl)-3-fluorophenyl)urea (162 mg; 88%).
