Versuchsvorschrift

135 g of benzothiazole and 121 g of allylbromide were mixed and the mixture was heated for 2 hours on a steam bath to solidify by crystallization. After cooling, diethyl ether was added to wash the crystals. After filtration and drying, the crystals obtained were recrystallized from ethanol. Melting point: 145°-147°C.
