Reaction Conditions

Reaction Steps

Combine 2-chloro-4-fluoro-N-(3-(1-methylpiperidin-4-ylamino)phenyl)benzamide dihydrochloride (Example 1, 48 mg, 0.134 mmol), dioxane (1 mL) and cyclopropylcarbonyl chloride (0.013 mL, 0.148 mmol). Shake and heat (106° C.) in a J-Kem® Reaction Block for 2 hr. Load onto a SCX column (Varian) and elute with 2 M ammonia methanol to give the free base of the title compound (54 mg, 93%). Following a salt formation method similar to that described in Example 1 gives the title compound as a white solid (47 mg): mp 133-6° C.; mass spectrum (freebase, ion spray): m/z=430.1 (M+1), 1H NMR (freebase, CDCl3): 8.31 (bs, N—H), 7.76 (dd, J=6.0 Hz, 8.6 Hz, 1H), 7.61-7.56 (m, 2H), 7.38 (t, J=8.0 Hz, 1H), 7.19 (dd, J=2.4 Hz, 8.3 Hz, 1H), 7.09 (td, J=2.4 Hz, 8.2 Hz, 1H), 6.96 (d, J=8.2 Hz, 1H), 4.62-4.53 (m, 1H), 2.80 (bd, J=11.5 Hz, 2H), 2.20 (s, 3H), 2.05 (td, J=2.2 Hz, 12.1 Hz, 2H), 1.83-1.69 (bm, 2H), 1.59-1.37 (bm, 2H), 1.21-1.13 (m, 1H), 0.99-0.89 (bm, 2H), 0.56 (bd, J=7.4 Hz, 2H). Analysis calc'd for C23H26Cl2FN3O2.0.8H2O: C, 57.46; H, 5.79; N, 8.74. Found: C, 57.16; H, 5.73; N, 8.70.
