TEA (l27. l mg, 1.3 mmol, 2.0 equiv) and l-butyl-4-isocyanatobenzene (132.1 mg, 0.8 mmol, 1.2 equiv) were added dropwise. The solution was then stirred for 2 hours at RT. The resulting solution was concentrated under vacuum. The crude product was purified by Prep-HPLC with the following conditions: Column: XBridge Prep OBD C18 Column, 30x l50mm 5um; Mobile Phase A:Water (10 MMOL\/L NH4HCO3), Mobile Phase B:ACN; Flow rate:60 mL\/min; Gradient:50% B to 82% B in 7.5 min; UV 254\/210 nm; RTl :4.48. l-(4-Butylphenyl)-3-(3-phenyl-lH-pyrazol-4-yl)urea (30 mg, 14.3%) was isolated as a white solid.
