Reaction Steps

The title compound of Example 142 was prepared in similar manner as described in Example 134 except the key intermediate (R)-tert-butyl 3-((R)-2-(3-chloro-5-fluorophenylamino)-2-cyclopropylacetamido)piperidine-1-carboxylate was replaced with (R)-tert-butyl 3-(2-(3,5-dichlorophenylamino)acetamido)piperidine-1-carboxylate and the 4-amino-6-chloropyrimidine-5-carbonitrile was substituted for 6-chloro-N-isopropylpyrimidin-4-amine. 1H NMR (300 MHz, CD3OD) δ 8.08 (s, 1H), 6.63 (t, J=1.89 Hz, 2H), 6.48 (d, J=1.89 Hz, 3H), 5.72 (s, 1H), 3.78-4.05 (m, 5H), 3.42-3.60 (m, 3H), 1.90-2.08 (m, 2H), 1.80 (td, J=3.59, 8.97 Hz, 3H), 1.65 (td, J=3.21, 8.03 Hz, 2H), 1.13-1.39 (m, 13H).
