Versuchsvorschrift
To a solution of ethyl 4-(isopropylamino)-2-(methylthio)pyrimidine-5-carboxylate (16.4 g, 64.4 mmol) in anhydrous THF (100 mL) was added LiAlH4 (6.1 g, 0.16 mol) in portions at 0° C. under N2 atmosphere. The reaction mixture was stirred an additional 30 min at RT and was quenched by the addition of water (6 mL) followed by aqueous 2 N NaOH (6 mL). The suspension was filtered and the filtrate was concentrated to give (4-(isopropylamino)-2-(methylthio)pyrimidin-5-yl)methanol (13.5 g, 98% yield), which was used without further purification. 1H NMR (400 MHz, DMSO-d6): δ 7.79 (s, 1 H), 6.37 (d, J=7.6 Hz, 1 H), 5.10 (t, J=5.6 Hz, 1 H), 4.28-4.20 (m, 3 H), 2.38 (s, 3 H), 1.13 (d, J=6.4 Hz, 6 H).
