Procedure

A solution of product from step (c) (13.56 g) in ethyl acetate (68 mL) was stirred under a hydrogen atmosphere with 5% palladium on carbon (1.36 g, wet paste) for 3 hours. The catalyst was then removed by filtration and the filtrate was concentrated in vacuo to give the title compound as a pale yellow oil (10.93 g). GC retention time 15.2 mins

Workup
