Participants

Reaction Steps

To a solution of 0.85 mL (8.28 mmol) of cyclohexanone and 1.0 g (8.75 mmol) of 2-amino-4-methylthiazole in 10 mL of tetrahydrofuran was added 0.5 mL (8.75 mmol) of acetic acid and 4.64 g (21.8 mmol) of sodium triacetoxyborohydride. After stirring for 16 hr at rt, a further 0.45 mL (4.37 mmol) of cyclohexanone and 0.926 g (4.37 mmol) of sodium triacetoxyborohydride was added and stirring continued for 72 hr at rt. Ethyl acetate (15 mL) was added and the mixture washed with saturated sodium bicarbonate (2×15 mL) then dried (Na2SO4). Purification by chromatography on silica gave the title compound.
