Reaction Steps

Pyridine (0.11 ml) was added to a solution of methyl 2-(5-(4-aminophenyl)thiazole-2-carboxamido)-3-methylbutanoate (Intermediate 2, 150 mg) in DCM (3 ml) and the reaction mixture was stirred for 5 minutes. 4-tert-butylbenzoyl chloride (0.125 ml) was then added and the reaction mixture was stirred for 1 h. The reaction mass was quenched with water. The organic layer was dried over Na2SO4 and evaporated under reduced pressure to get dark brown solid which was purified by silica gel column chromatography (EtOAc:CHCl3, 2:8) to get off white solid. The solid was crystallized in CHCl3/pet ether to give the title compound. Yield: 160 mg (72%) white solid. 1HNMR (DMSO-d6, 300 MHz): δ 10.38 (s, 1H), 8.76 (d, 1H), 8.41 (s, 1H), 7.94 (d, 2H), 7.91 (d, 2H), 7.8 (d, 2H), 7.58 (d, 2H), 4.33 (m, 1H), 3.69 (s, 3H), 2.27 (m, 1H), 0.95 (d, 6H); MS (ES+): m/z 494 (M+1).
