Reaction Steps

Trifluoroacetic acid (0.25 ml) was added to a solution of 4-anilino-5-bromo-2-{4-[3-(t-butoxycarbonylamino)-1-propynyl]anilino}pyrimidine (Method 25; 30 mg, 0.06 mmol) in DCM (1 ml). The solution was left to stand for 3 hours and volatile material was removed by evaporation. The residue was triturated with diethyl ether to give the product as a trifluoroacetate salt (25 mg, 81%). NMR: 4.0 (m, 2H), 7.2 (m, 2H), 7.4 (m, 2H), 7.5–7.7 (m, 4H), 7.8 (m, 1H), 8.2 (br s, 2H), 8.7 (s, 1H), 9.6 (s, 1H); MS (MH+): 394.3, 396.3.
