Sodium borohydride (1.74 g) was added to a solution of 5-(2-(tert-butyldimethylsilyloxy)ethyl)thiophene-2-carbaldehyde (12.4 g) (example 4, step b) in ethanol (120 mL) at 0° C. The resulting solution was stirred at 0° C. for 1 h. The reaction mixture was partitioned between brine and ethyl acetate. The organic layer was separated, dried over sodium sulphate, filtered and the solvent evaporated in vacuo to give the subtitled compound. Yield 12.1 g.
