Reaction Steps

N,N-dimethylformamide di-tert-butyl acetal (134 mg, 0.66 mmol) was added to a solution of 2-(R)-{[4-(4-chlorobenzoyl)piperidine-1-sulfonyl]amino}-3-methylbutyric acid (90 mg, 0.22 mmol) in toluene (2.5 ml) at 90° C. The reaction was stirred for 3 h and concentrated to give tert-butyl 2-(R)-{[4-(4-chlorobenzoyl)piperidine-1-sulfonyl]amino}-3-methylbutyric acid that was used in the next step with no further purification.
