Diisopropylethylamine → (S)-2-[6-(5-Chloro-pyridin-2-yl)-5,6,7,8-tetrahydro-pyrido[4,3-d]pyrimidin-4-ylamino]-2-(6-methoxy-pyridin-3-yl)-ethanol

Reaction Steps

A reaction mixture of 4-chloro-6-(5-chloropyridin-2-yl)-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine (55 mg, 0.20 mmol) and (S)-2-amino-2-(6-methoxypyridin-3-yl)ethanol (33 mg, 0.20 mmol) in acetonitrile (2 mL) and N,N-diisopropylethylamine (68 μL, 0.39 mmol) was subjected to microwave irradiation at 180° C. for 2 h. The reaction mixture was concentrated and purified by semi-prep HPLC (100×20.2 mm, C18 column; 25-50% CH3CN-water [10 mM Et2NH]) to give an off-white solid.
