실험 절차

Acetic acid (0.053 mL) was added to a mixture of 10-(4-(2-isopropylthiazole-4-carbonyl)-1-oxa-4,9-diazaspiro[5.5]undecan-9-yl)decan-2-one (example 280, step c) (335 mg) and (R)-7-(2-amino-1-hydroxyethyl)-4-hydroxybenzo[d]thiazol-2(3H)-one hydrochloride (WO2007027134, example 1, step d) (243 mg) in dry methanol with 3 Å molecular sieves at room temperature under nitrogen and stirred for 5 minutes. The mixture was cooled to 0° C. and sodium triacetoxyborohydride (131 mg) was added. The reaction mixture was stirred, warming to room temperature overnight. The mixture was filtered and evaporated. Purification was by preparative HPLC (Phenomenex Gemini®, Gradient: 10-40% acetonitrile in 0.1% aqueous formic acid). The fractions containing product were combined and freeze-dried to afford the titled compound as a white solid. Yield 0.032 g.
