Participants

Reaction Steps

A solution of 4-(3-phenylpyrazolo[1,5-a]pyrimidin-6-yl)thiophene-2-carbonyl chloride (5-4, 5.0 mg, 0.015 mmol, 1 equiv), diisopropylethylamine (60 TL, 0.030 mmol, 2.0 equiv), and N,N-dimethylethane-1,2-diamine (41 TL, 0.016 mmol, 1.1 equiv) in dichloromethane (1 mL) was mixed and allowed to stand for 8 hours. The reaction mixture was washed with aqueous half-saturated sodium bicarbonate solution (0.5 mL). The organic layer was dried over sodium sulfate and concentrated to give N-[2-(dimethylamino)ethyl]-4-(3-phenylpyrazolo[1,5-a]pyrimidin-6-yl)thiophene-2-carboxamide (5-5) as a yellow solid. LRMS m/z: Calc'd for C21H22N5OS (M+H) 392.2, found 392.3.
