Procedure

A suspension of 2-[5-chloro-2-(5-methyl-6-oxo-5,6,8,9-tetrahydro-7-oxa-5-aza-benzocyclohepten-2-ylamino)-pyrimidin-4-ylamino]-3-fluoro-N-prop-2-ynyl-benzamide (108 mg) and gold (III) chloride (20 mg) in acetonitrile (20 mL) was stirred for 16 hours and filtered. The filtrate was concentrated and purified by silica gel chromatography to provide 2-{5-chloro-4-[2-fluoro-6-(5-methylene-4,5-dihydro-oxazol-2-yl)-phenylamino]-pyrimidin-2-ylamino}-5-methyl-8,9-dihydro-5H-7-oxa-5-aza-benzocyclohepten-6-one (80 mg): 1H NMR (300 MHz, CDCl3) δ 10.10 (bs, 1H), 8.20 (s, 1H), 7.84 (dd, 1H), 7.46-7.34 (m, 4H), 7.14 (bs, 1H), 7.06 (d, 1H), 4.96 (dd, 1H), 4.82 (t, 1H), 4.56-4.50 (m, 2H), 3.45 (s, 3H), 2.92 (t, 1H).
