Step c; 4-Formyl-2,2-dimethyl-oxazolidine-3-carboxylic acid tert-butyl ester (12c); A solution of dimethylsulfoxide (8.10 g, 103.71 mmol) in dichloromethane (10 ml) was added dropwise during 25 min to a solution of oxalyl chloride (6.58 g, 51.9 mmol) in dichloromethane (80 ml) at -78 0C. At the end of the addition the reaction solution was warmed up to -60 0C, and a solution of the alcohol 12b (8.0 g, 34.6 mmol) in dichloromethane (60 ml) was added dropwise during 50 min. N,N-diisopropylethyl amine (36 ml, 200 mmol) in dichloromethane (5 ml) was then added to the reaction mixture -45 0C during 30 min whereafter the reaction mixture was allowed to warm to 0 0C during 10 min. The reaction mixture was then transferred to a separation funnel charged with ice-cold 1 M HCl solution (130 ml). The two phases were separated and the aqueous phase was extracted with dichloromethane. The combined organic extracts were dried and concentrated which gave the title compound (7.89 g, 99%). The residue was used in the next step without further purification.
