1-Naphthalene ethanol (10 g) was treated with benzyltrimethylammonium hydroxide (Triton B®; 0.9 mL of a 40% solution in methanol) and the resulting mixture stirred in vacuo for 30 minutes. The mixture was then cooled to 0° C. and treated with tert-butyl acrylate (8.19 g). The resulting mixture was slowly warmed to room temperature and stirred overnight. The crude mixture was subsequently absorbed onto aluminium oxide (30 g) and eluted with diethylether (200 mL). The organics were concentrated to give a crude material (16.6 g) which was purified by flash silica chromatography eluting with 1:8, diethylether:hexane to give the subtitled compound (12.83 g).
