To 100 ml. of 1.0 M borane in tetrahydrofuran cooled in an ice bath under nitrogen is added dropwise, 27.8 g. of p-decyloxybenzoic acid in 300 ml. of tetrahydrofuran over a period of 45 minutes. The mixture is stirred at room temperature for 6 hours and poured onto ice, diluted with water and 10 ml. of concentrated hydrochloric acid. The mixture is filtered and the solid washed with water to give white crystals. Recrystallization from ethanol gives white plates, m.p. 57.5°-59° C.
