Procedure

In a 25 ml 3-neck RBF was equipped with a magnetic stirrer and CaCl2 guard tube was added tert-butyl (2-chloro-5-fluoropyrimidin-4-yl)(3-(hydroxyamino)phenyl)carbamate (0.409 g in 5 ml DCM). The reaction was cooled to −40° C. and acryloyl chloride (0.114 g in 3 ml DCM) was slowly added. The reaction mixture was warmed to room temperature and stirred at room temperature for 30 min. The reaction was monitored on TLC using hexane:ethyl acetate (7:3) as mobile phase. The reaction was complete after 30 min and was poured in water (100 ml) and basified using sodium bicarbonate solution. The reaction mixture was extracted with DCM (2×25 ml) and the combined organic layer was washed with brine solution, dried over sodium sulfate and concentrated completely under reduced pressure at 40° C. Crude material was purified by using column chromatography. Product was eluted with 14% ethyl acetate in hexane to give, after concentration, 0.250 g of tert-butyl (2-chloro-5-fluoropyrimidin-4-yl)(3-(N-hydroxyacrylamido)phenyl)carbamate
