반응 단계
A solution of 3-chloro-5-(5,6,7,8-tetrahydropyrido[4′,3′:4,5]thieno[2,3-d]pyrimidin-4-ylamino)phenol hydrochloride from Example 65A (150 mg, 0.41 mmol) and (2E)-4-(dimethylamino)but-2-enoic acid hydrochloride from Example 1A (94 mg, 0.57 mmol) in a mixture of DMF (2 mL) and THF (4 mL) was treated with DIPEA (263 mg, 2.03 mmol) and TBTU (197 mg, 0.61 mmol). The mixture was stirred at rt overnight and then directly purified by preparative HPLC. The product was triturated with tert-butyl methyl ether and collected by suction filtration to yield 52 mg (29%) as tan crystals.
