Isopropanol → 1-(Aminomethyl)cycloheptanol hydrochloride

Participants

Reaction Steps

Acetyl chloride (264 ml) and tetrahydrofuran (191 ml) were charged to a vessel containing 2-propanol (1143 ml) maintaining the temperature at 10° C. to 15° C. 1-(aminomethyl)cycloheptanol (381 g) in tetrahydrofuran (1613 ml) and tetrahydrofuran (381 ml) were charged maintaining the temperature at 10° C. to 15° C. The reaction mixture was stirred for 50 minutes and filtered. The filter cake was washed with premixed tetrahydrofuran/2-propanol [tetrahydrofuran (267 ml), 2-propanol (114 ml)], and tetrahydrofuran (1905 ml). The filter cake was dried at 40° C. for 23 hours to provide the title compound as a colourless solid (464 g).
