Reaction Conditions

Reaction Steps

A mixture of 4-(2-phenylamino-thiazol-5-yl)-phenol (35 mg, 0.130 mmol), 1-chloro-3-dimethylaminopropane hydrochloride (27 mg, 0.170 mmol, 1.3 equiv), and sodium tert-butoxide (29.6 mg, 0.299 mmol, 2.3 equiv) in 1-butanol (0.2 mL) is heated to 100° C. (using a preheated oil bath) for 3.5 h. The reaction mixture is allowed to cool to RT and concentrated in vacuo. Purification of the crude material by silica gel (10 g) column chromatography (CH2Cl2/MeOH, 90/10→80/20) affords the title compound as a reddish solid: ES-MS: 354.0 [M+H]+; single peak at tR=6.27 min (System 1); Rf=0.09 (CH2Cl2/MeOH, 90/10).
