To a solution of (S)-6-(5-cyclopropyl-1H-pyrazol-3-ylamino)-5-fluoro-2-(1-(4-fluorophenyl)ethylamino)-4-iodonicotinonitrile (Example 134, 0.07 g, 0.14 mmol) and DIEA (0.023 g, 0.18 mol) in n-BuOH (1.5 ml) was added isopropylamine (0.16 g, 2.7 mmol). The reaction was then heated to 185° C. under microwave conditions (1 hour×4 cycles). The reaction was then cooled to room temperature, DCM (10 ml) was added, and washed with 10% aqueous Na2S2O3. The organic layer was then dried over Na2SO4, filtered, and then concentrated. The resulting oil was purified by reverse-phase column chromatography (5-50% ACN) to give the title compound (0.031 g, 51%). 1H NMR (400 MHz, CD3OD) δ 7.36-7.33 (m, 2H), 7.04-7.00 (m, 2H), 5.99-5.59 (br s, 1H), 5.14 (s, 1H), 4.29-4.23 (m, 1H), 1.87-1.83 (m, 1H), 1.52 (d, J=7.0 Hz, 3H), 1.25 (d, J=6.2 Hz, 6H), 0.95-0.94 (m, 2H), 0.65-0.63 (m, 2H). MS: Calcd.: 437. Found: [M+H]+ 438.
