5317-33-9, 3-(4-Methylpiperazin-1-yl)propan-1-ol is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,5317-33-9
b. 7-[3-(4-Methyl-piperazin-1-yl)-propoxy]-4-piperidin-4-yl-quinazoline; Solid KOtBu (1.36 g, 12.1 mmol) was added in one portion under air to a homogeneous solution of 4-(7-Fluoro-quinazolin-4-yl)-piperidine-1-carboxylic acid tert-butyl ester (3.33 g, 10.1 mmol), as prepared in the preceding step, and commercial 3-(4-methyl-piperazin-1-yl)-propan-1-ol (1.50 g, 9.50 mmol) in dry THF (10 mL), while stirring on an ice bath. Following KOtBu addition, the ice bath was immediately removed, and the resulting homogeneous amber solution was stirred for 6 hr. 6 M aqueous HCl (10 mL, 60 mmol) was then added in one portion, and the reaction was stirred overnight (mild bubbles were seen following HCl addition, but these subsided after 15 min). The reaction was then partitioned with 9:1 DCM/MeOH (50 mL) and 2.5 M NaOH (28 mL, 70 mmol), and the aqueous layer was extracted with 9:1 DCM/MeOH (1×50 mL). The combined organic layers were dried (Na2SO4) and concentrated by rotary evaporation at 90 C. to provide the crude title compound as a clear yellow oil (3.79 g, ?102%? crude yield). LC/MS (ESI): calcd mass 369.3, found 370.2 (MH)+.
The synthetic route of 5317-33-9 has been constantly updated, and we look forward to future research findings.
