Tetrahydrofuran → Tert-butyl (2-{4-[4-(5,5,8,8-tetramethyl-5,6,7,8-tetrahydronaphthalen-2-yl)thiazol-2-yl]piperidin-1-yl}ethyl)carbamate

Participants

Reaction Steps

10 ml of THF and 200 μl of glacial acetic acid are added to 200 mg (0.46 mmol) of 4-[4-(5,5,8,8-tetramethyl-5,6,7,8-tetrahydronaphthalen-2-yl)thiazol-2-yl]piperidine hydrobromide, and 154 mg (0.92 mmol) of tert-butyl (2-oxoethyl)carbamate are added. 195 mg (0.92 mmol) of sodium trisacetoxyborohydride are subsequently added, and the reaction mixture is stirred at room temperature for 24 h. The reaction mixture is filtered, the mother liquor is evaporated, and the residue is purified by preparative HPLC, giving “A37”;
