(2-Methyl-1,3-thiazol-4-yl)methanol → 2-Amino-4-(2,3-dihydro-1,4-benzodioxin-6-yl)-6-[(2-methyl-1,3-thiazol-4-yl)-methoxy]-3,5-pyridinedicarbonitrile

Participants

Reaction Steps

100 mg (0.26 mmol) of 2-amino-4-(2,3-dihydro-1,4-benzodioxin-6-yl)-6-(phenylsulfanyl)-3,5-pyridinedicarbonitrile [prepared analogously to Kambe et al., Synthesis, 531-533 (1981)] are, together with 44 mg (0.39 mmol) of potassium tert-butoxide and 334 mg (2.59 mmol) of (2-methyl-1,3-thiazol-4-yl)methyl alcohol, stirred in 5 ml of 1,2-dimethoxyethane at room temperature overnight. The reaction solution is concentrated under reduced pressure and the residue is then purified by preparative HPLC on reversed-phase silica gel.
