Procedure
A solution of (1S,3R)-2,2-Dimethyl-3-((2-(methylsulfonyl)-5-(trifluoromethyl)pyrimidin-4-yl)amino)cyclobutanol (1.0 equiv.) and (4-(2-fluoropropan-2-yl)pyrimidin-5-yl)methanamine dihydrochloride (1.3 equiv.) were combined in dioxane (0.4 M) and stirred at ambient temperature. After 1 h, the solution was heated to 75° C. After 16 h, the solution was concentrated under reduced pressure and after standard work-up the title compound (50.9% yield) was obtained. The absolute stereochemistry was determined, using the chiral intermediate, as described herein for other compounds. 1H NMR (400 MHz, DMSO-d6) δ (ppm) 9.01 (s, 1H), 8.47-8.67 (m, 1H), 7.94-8.14 (m, 1H), 7.78 (br. s., 1H), 6.07 (d, J=7.81 Hz, 1H), 4.66-4.91 (m, 2H), 3.35 (br. s., 1H), 1.96-2.22 (m, 1H), 1.62-1.82 (m, 6H), 0.54-1.23 (m, 6H); MS(ESI) m/z 429.3[M+1]+.
