Procedure: In a pressure tube tert-butyl (3-aminophenyl)(methyl)carbamate (2.0 g), 2,4-dichloro-5-fluoropyrimidine (2.25 g) and DIPEA (2.32 g) were added in 1-butanol (15 ml). The reaction mixture was heated at 120° C. for 3 hr. The reaction was monitored on TLC using hexane:ethyl acetate (7:3) as mobile phase. The reaction was complete after 3 hr. After completion of the reaction, the reaction mixture was allowed to cool at room temperature. The reaction mixture was poured into water and extracted with ethyl acetate (3×25 ml). Ethyl acetate layer washed with brine solution, dried over sodium sulfate and concentrated under reduced pressure at 40° C. Crude material was purified by using Combiflash chromatography.
